Glow plus solenoid....help please!!

[joeyaguirre21]

So glow plug solenoid went out a while back replaced wih new one and it was getting hot and went out. So i replaced it again and its still getting hot. So i have my main power on a big stud the glow plugs on the other big stud and the pink with black strip wire on the switch side and the green wite on the ignition side. After running or driving it for a while it still stays hot and i have power all the way around which i know i sshould have. Please help.

I'm certain folks like Warthog and Antennaclimber will have much sounder council. But based on your pic and symptoms the first thing I would check is whether or not you have an isolated relay. The system works by grounding the relay coil when energized. It sounds like the coil has power applied to it 100% of the time.

Need more information, what part number did you get for your relay? Correct ones are these GP Relay is NAPA# ST85, Advance Auto #S603 or suitable substitute (one with an isolated ground)

Nvm I got it guys. So I eliminated the 2 small wites which are pick with black strip and green wire. And just ran a wire from the solenoid stud that has an "S" on there to a push button switch and ran a wire from the other end of the switch to a power source. So it'll active the glow plugs only when i push it.

I'm going to say that first off you have the wrong solenoid. like posted earlier. ST85 is what you want.

If you have been driving around with the relay on, you had better check your glow plugs to make sure you haven't fried any of them. Once a couple of them go bad the rest will follow suit.

Excellent point.

To help prevent this, you may want to consider performing the firewall resistor bypass and feed the glow plugs 12v.
