No 4wd and buzzer going off under dash (BJ73)

[Slideways]

Im in Lower Hutt. Couple of things to try now thanks for the input guys.

Brother is buying a SWB cruiser tonight possibly so might be good for me to use as a reference

[Slideways]

Ok so have taken the gauge cluster to bits and its clean as a clean thing inside, I did try blow it but no dust at all and no sign of moisture.

I'll try take the sterring column covers off and see if there are any loose connections but the fact that I do have power to the dash makes it unlikely... but Im open to anything!

Im thinking of calling an auto electrician tomorrow on my day off. I can see it costing a fortune but I really am getting no where

My brother is going to make the deal on a SWB cruiser of his own tonight so might be able to steal the dash cluster from that and see what happens.

Oh yeah and the buzzer is definitely not anything shorting, its a little black box next to the steering column. Which has to be a speed limit warning.

I'd be real suprised if it was anything to do with the dash. I'd be checking out for alternator trouble for the buzzer, and check the vacuum/electrical connections on the transfer case underneath. Water is a bastard.

try pulling the plug off the back of the alternator then start it see whats happening then as i said the auto electrician did that and told me was the alternator

Be intresting to find the cause keep us updated

[gazza]

Any news yet on what the problem was???

[Slideways]

Not yet no. Alternator seems fine, getting 14volts on idle.

Going to get an auto electrician to have a look this weekend hopefully.

so what was the verdict?

[Slideways]

Funny you should ask. Been really busy the last few weeks but had organised to have it checked out as a perk job. But that never eventuated due to it being too tall to get into the garage and bad weather for weeks on end.

So last night I dropped it off to a local auto electrician. Had a real cnut of a time getting it there, first it kept stalling when I put it into drive (its an auto) then it was coughing and spluttering and finally died so had to pull over real quick. Battery was dead as a dead thing and it was pissing down in heavy peak hour traffic. Joy.

Ended up parking gf's car nose to nose and charging the battery with her car for a few minutes. Got it started and when to pull out and it died. Getting a little f'd off now lol. JUST managed to get it started and left headlights off (its dark by now) and drive with hazards.

Got to auto electrician an hour after he should have closed up. Engine stalls and steam coming out of bonnet. Yay. Looks like radiator fan may not be working along with other electrical problems.

So parked it with bonnet open waiting for it to cool down then filled with hot water. Wrote a big list of Faults for the guy and locked it up... low and behold the ####### bonnet won't close. The latch just isn't working (this has never been a problem before).

Managed not to set fire to it and left it there.

Now expecting a big bill, but hopefully it'll all get fixed so I can concentrate on finishing the new 2.5" exhaust and wiring up the oxygen sensor (it never had one, due to having after market extractors, so probably why it uses so much fuel).

Sounds awesome with the new exhaust and free flow muffler though. This is the first ever welding job I've done - just recently bought myself a welder to learn on. After 45min of practice I bought some pipe and got going lol. Now seriously thinking of fabricating some brackets and piping for fitting a supercharger with my new found welding skills (if you can call it that lol).

Sorry for the rant

wow you have patience i probably would have tourched the bitch before getting to sparky... lol let us know hwo you get on.

Wow Im really curious how you are running the 12v engine with 24v cruiser electrical system, do you have 2 batteries and just running the engine electrics off one? you mentioned it's charging at 14v so you have a normal 12v alternator. How does it run the rest of the 24v electrics like the 4wd solenoid from 12v? do you have 2 alternators?
Reason I ask is because Im about to do a similar conversion.

problem sounds a lot like water has got into the relays and some sensors under the bonnet, not stuff behind the dash.
when I 'parked' my cruiser in a stream the windscreen wipers came on for a day but then I guess it dried out and its fine now.

Its been at the electricians for a week and a half now. The guy has been held up with urgent jobs etc... was really hoping to go 4wd'ing with my brother since he recently bought a cruiser but was let down again. Just more waiting...

Its running a holden v6 motor with standard (holden) 12v Alternator. Single battery, most relay's have been swapped to 12v. I recently changed the heater/blower motor to a 12v one because the old 24v one was pathetic with only 12v's power it but other than that nothing else has been a problem. Apart from small things like the 24v voltmeter barely showing anything for obvious reasons.

I bought it a couple of months ago and it was all fine. No probs with 4wd engaging (well at least the light used to come on).

I hope its something simple like water in relays like you say but no luck yet.

Dosent that usually mean he's putting it off coz he's not too keen to look at it

You might have to give him a timeframe so you get the thing back before the weeks (months) roll on

Holy crap I finally got it back!!

Main problem was the fusebox behind the drivers kick panel, the connections on the back were stuffed. It has a leak somewhere around there when it rains so thats most likely where the problem came from. Other than that there was some dodgey wiring that needed sorting out.

All is fine and dandy now, will have to test out the 4wd system this weekend hopefully.

I've finished the exhaust and it sounds awesome but not sure about these new exhaust noise laws!

The exhaust is: tuned length extractors -> 2" mandrel -> 2in1 collector -> 2.5" with single high flow muffler -> 2.5" over rear axle. Sooooo much better than what was on it when I bought it. Also welded in a threaded adaptor for an oxygen sensor - which will hopefully improve its thurst.

Next job is finding the leak, fixing rust and fitting a water temp gauge.

[Slideways]

Can anyone tell me if the back/rear doors from a 1992 Prado (4dr) would fit my BJ73?

They look identical to me, and knowing toyota they are likely to have re-used some parts.

are you sure it hasn't been swimming? and got water inside up to the fuse box?

[Slideways]

Probably has in the past - it is 22 years old and rough example at that! But I know for a fact that water does leak in during any decent rain, I could see water dripping from somewhere under that dash (edit: most likely from where the aerial wiring is coming through or possibly through the fold down screen gap) while it was parked up. I ended up putting a cover over it until I can find where the leak is.... since it hasn't stopped raining for months.

Eitherway its fixed now so can continue with getting the rest up to standard. Exhuast is done - after rust work I'll make a snorkel Then rust proof everywhere I can, then fit a supercharger

[Slideways]

Didn't stay dry for long

All good though, 4wd and everything works again
