Glow plug problems

[WideLoad]

Having problems getting my plow plugs going on a 2LT, tested the relays and they're all good so assumed the timer was faulty. I wired a push switch in basically taking the ignition power leading into the glow plug timer and switching it to the the 2 wires leading back off to the relays. Now when I switch the relays on the 80amp fusable link blows. Have I wired this in wrong? Or is there something else goin on?

Hi .... two questions ...
Where in NZ are you ??
What make of truck is it ??
I had an issue with the timer on my Isuzu and found that the glow circuit is a bit strange. (pic below )
It sounds like there is a short happening somewhere as the glow circuit normally draws about 30 amps.

I am trying to remember how I did mine ... I may have to have a look under the bonnet tomorrow ...

Sorry,
It's a LN65 Hilux that was originally a 2L non turbo and I have now put a 2LT turbo in and I'm in Tauranga.

put a external glow plug timer on it.

Just had the exact same symptoms on a mates Mu. Found two glowplugs were stuffed. Pull the glowplugs out and check each one with a set of jumper leads.

just checked all the glow plugs and they're all good, but noticed the ones in the new motor are 6v and the ones from the original motor are 7v. Don't think this would make much difference though.
Was also wondering, the power cable to the glow plugs bolt on top of the current sensor to the block, wouldn't this cause a short if it's not insulated from the block some how?

common problem with them is people don't put the insulators back on properly and short out the glow power. blows one of the fuseable links.

Ok, I'm pretty sure I don't have an insulator, I'm guessing it's some sort of washer with a sleeve that insulates the bolt as well? Would repco have them? Sorry just never worked on these before.

Definatly missing the insulator and I've found the part number for it so can hopefully get one off the local toyota outfit. Can hopefully get the clunker running after that.

Now you know what you are looking for go down to ya local wreckers or pick-a-part ... Much cheaper than Toyota
