new winch motor time

[new2zukes]

well i burnt out my old winch motor and solonoids and am going to be getting the bigger winch motor for it (its an 8274) had a 4.6hp motor on it before and am looking at a bigger one, after a bit of emailing to fullyequipt i got a quote for a 6hp bosch mh xp9500 12v for $665 plus gst would this be the go??? and would i need bigger solenoids if so i need to get some more as i have burnt them out too. im alo not sure what solenoids i will need so basically i would like to know what the best option will be. im planning on doing the winch challenge this year if i get my truck all up to scratch (trying to find a suzuki windscreen surround is a bit of a mission) so if anyone can give me a little help that would be great.

cheers

That is the motor I am running and that is a pretty good price. I run the standard warn solinoids sweet as.

Whe you want a good freespool for it let me know, I can get one engineered that will be nearly as good as mine.

[suzukisport]

We are running Warn solinoids like meatc and same 6hp motor. Warn solinoids seam to do the job just fine

[new2zukes]

good stuff will try get some will order winch motor soon

[darinz]

The only time the Warn solenoids play up is if you don't have enough battery power. If this runs low then Amps go up and they can weld shut! 4 post aftermarket solenoids are a better options but I wouldn't replace them unless you start having issues.

[new2zukes]

hey darin i am replacing them as they have already burnt out. i just need to get some more solenoids the ones where i use only 2 solenoids. i had solenoids from cole hersee boston usa on there. i am running 2 of the same sized batteries as what dan is running in his winch truck so battery power should be ok. do you know where i can get some good priced solenoids as i have been quoted $183 for 2 high amp solenoids which seems a tad steep to me. any info would be great thanks.

6hp X 705W per HP = 4230 watts / 12v = 352 amps

THAT is the current you will be switching when the motor is developing full power, more, LOTS more, if the motor is stalled.

How hard would it be to use the existing solenoids to switch heavy starter-motor type solenoids? Thems are designed to handle high contact currents

Please check my math, but I am pretty sure I haven't fkd up.

[new2zukes]

yes they are but starter solenoids are intermittent use not continuous like winch motors ( i think this is what you are asking) and yes your maths is correct apart from the answer was 352.5 hehehe thanks for that as this is what i was after, how many amps the solenoids have to take continuously.

[Moriarty]

If your winch solenoids are cooking out or the contacts are failing, then they too are not rated correctly.

The starter motor solenoids that I am thinking of are the old outboard types, (NOT outboard motors) that merely make the electrical connection. The starter motor has a bendix throw-in gear for engagement of drive, NOT germane here.

Its the solenoid that I am thinking of.

As per below....

Those are similar to the original 4 pack warn ones. THe newer ones are twin pole so you only need two to do the same job. Getting big enough ones is not the problem.

The usual reason they burn out is lack of flow bumping up the amps due to voltage drop. Solution BIG cables form bat to solenoid to winch including a big fat earth from battery to winch.

I am using the old fashion 4 pack solenoids and have near stalled the 6hp winch a number of times with no issue. 2 Big batteries in good condition and as short as possible 90mm2 welding cable for leads.

[darinz]

I always used Come-up Solenoids that I got from Union Car Spares. And yes you'll be looking at $200 ish anyway you go. With these solenoids I have burnt out a 6hp 12v while running 24v through it! Seriously it melted the motor completely as it was a twin motor setup so keep spinning and melting. The solenoids were fine after this and did many more competitions and are still going fine. Keep the volts high and the amps low like Meatc has said.

But seriously, people always go on about the solenoids when it is a power supply issue and the solenoids are the weak point. When I burnt the motor I also had a switch and that burnt out so was much safer and cheap to melt the switch than have the solenoids weld shut!!!!!!

[new2zukes]

thanks for that i will get this sorted sooner rather than later as we have a club run coming up soon and want to try the new winch motor and ground anchor to see if its going to be a goer. what would be the lowest volts that you would let it drop to? mine on the old solenoids and the old motor running same battery and cable set up as dans would go down to 10 volts is this bad?

[suzookyman]

Hey Martin, well it looks like i cant get the soft top 413 i was hunting down but if i come across one i will let you know

It all depends. If you have efi then at 10v the ecu will most likely cutout anyway. One thing you also need to be careful of is where the volt meter is wired in. If it isn't at the battery then the reading can sometimes be incorrect. I found this out the hard way!
I'd careful at 10v but for short pulls it is probably OK. At 10v then to get the same hp the amps will be about 20% higher. So if you are under serious load then you could be up around 500amps. The 6hp at stall is using 500amps at 12v so it is quite easy to see the extra load.

FYI when i ran the 6hps with 24v then it dropped to 20v with the instant I hit the switch BUT that is a bit different and probably a saving grace for them. ie 20v into a 12v motor.

[new2zukes]

hey thanks for that i have emailed union car spares and they want $246.60 inc gst for a solenoid pack fully equipt want $211.54inc gst a mate of mine thinks he can get them for $120-$150 but havent got the right specs for them yet.

hey al that ok i have found a fibreglass one for a reasonable price so im sorted now, just need a few bits n pieces then im ready to race.

[new2zukes]

i have been thinking if these traditional solenoids are over $200 and the sealed units such as this one http://www.trademe.co.nz/Trade-Me-Motors/Car-parts-accessories/Other-accessories/auction-354963693.htm are only $165 why do people not use these ones more? do they not take the extra load of a bigger motor or do they not last as long? just curious that's all.

[darinz]

I'm a big fan of using the older 2 soldnoid system as it means you can carry a spare and it is only half the cost. But upon saying that I've never needed to replace one during an event and the only failure was most likely water / corrosion damage anyway.

I haven't gone to a sealed unit as haven't needed to replace solenoids since they became an option. I do however have one sitting at home that was suposed to go onto an 8274 with a 6 hp motor, but you can guess where that motor is and why I'm not using it myself!

[jeremy]

We've been running the sealed units that look just like the tigerz11 one in that auction, since 2004 (they were the cool new thing back then) on our 24v twin motor winch and have had zero issues. They are mounted next to the winch so would get submerged from time to time.

We bought ours from Traxion, and at the time they weren't cheap, but we were looking to buy something we could set and forget. I'm not sure if the Tigerz11 units just look alike of if they are made by the same manufacturer?

[flyingbrick]

they both import from china im told... so its possible they are the same units.

[Mudhog]

Hi Flyingbrick,

Tigerz11 have a New Solenoid due out very soon called the TG Thompson Solenoid, it's been designed and made for Tigerz11 from better quaility materials and will be standard with all there winches shortly. I have a sample and it looks pretty solid and different to the Titan Solenoid you are all talking about.

I will try and upload a picture of it.

There is now a listing on Trademe for the TG Thompson Solenoids.

Cheers Brett

[Mudhog]

I've put a picture in build's showing the new TG Thompson Solenoid- well part of a picture!!!

Cheers Brett

[new2zukes]

well have just perchased the tg thompson solenoids, should be ready for our next club run so i can test it out.http://www.trademe.co.nz/Browse/Listing.aspx?id=355409046 not a bad price too. thanks for all your input and will post a few pics up of my truck once i have done a few extra things to it like modify my bonnet hump for the 3rd time.
