Glow plug relay in cucv

[Bigred]

I replaced a non working glow plug relay in my dad's CUCV with part # GRP109. The new unit works fine except that we noticed after the dash light cycles off the relay stays on for another 8-9 seconds. This is after the initial 9-10 seconds. I am worried the glow plugs will burn out from staying on too long. We tried switching the small wires on the relay, this made no difference. Any suggestions ?

Thanks

Check cucvelectric.com there is a trouble shooting guide on their site. Really good guy to deal with.

The glow plug relay MUST be the same as the one you removed. Something about the ground being internal i think.
Googling that part number brings ups ford truck results. There are lots of people on steelsoldiers who have ruined their glowplug systems using that relay

Go get a napa st85 or equivilent. CUCV electric is a great sight as well.

Also dash light should only come on when relay it activated & visa versa. Sounds like wrong relay as said or wired wrong.

I dont believe that. Read the FAQ,
Many people have destroyed their gp systems using a "ford" relay, the website posted is great. Or you can look for a NOS on flmv, or saturn surplus
