i have continuous duty solenoids laying around. do i really need a new $ 110.00 dollar gpr also i know stancor makes a great replacement for my faulty gpr but i dont want to have to go to town and traipse all over to find one..

any comment , ideas...

 

If you have some relays that are rated for the task and you know how to wire them, there is no reason you cannot do that.
I'm currently using my intake air heater relay as a glow plug relay. I had deleted the IAH before and it was just sitting there next to the glow plug relay. When the GPR failed one morning, it was a simple matter of moving the wiring. Been that way for about 3 years now and no plans to change it until it fails.

 

sounds good, whats the downside to not having an AIH any more??

also i live in cold country...

 

There isn't a downside to deleting the AIH delete, most guys remove it anyway because it does basically nothing. Remove the AIH from the spyder and plug the hole, then use your AIH relay as a GPR. Nice thinking on that Kwik!

 

^^^ What both these guys said.

If you're asking this question, you have a pretty-good handle on what you're doing.

Let your inner-engineer be your guide.

BTW, Kwik knows his stuff. It would be a good idea to follow his advice. Diesels and cold areas are his expertise.

He's BTDT.

Thank you very much Marv.

If you all think about the design of the GPR vs the AIH relay, the AIH relay being nearly twice as tall as the GPR....
Now look at the element that it has to drive. Basically an oven coil mounted in the intake stream.
When it comes on it stays on for a long time. That requires a pretty hefty continuous duty relay - a perfect candidate for use as a glow plug relay.
