Re: Diesel won\'t start

If the relay is not cycling, it could be bad or the temp sensor is thinking it is hot enough and not kicking it on. I havent messed with my GP system yet but i can send you a schematic if you want.

This is the reason some people put a switch and bypass the controler.
Do a search and you will find the direction on how to rig one up, or you could change the controler.

thanks guys but i may have just had a loose wire /forums/images/graemlins/smirk.gif. but one thing thats bothering me is it would'nt hit a lick and it was like 75 here on the mountain but when i fully connected the loose wire it fired right up?

When you have a loose wire, as soon as you have a high demand in current it will disconnect, the small area that is touching will act like a fuse and burn and no more contact.

Re: Diesel won\'t start

ok i was wrong about the "loose conection" but i did finally find the problem it was the little in-line temp switch for the gp system i bypassed it and it is working fine dont know why it even got one it works fine without it
thanks,
