Glow plug push button problems

[kabar1]

i have replaced the glow plug push button, which came with the truck whem i bought it, the switch will work for a very short time then fry its self out, i got a 12 volt switch, it is 12 volt right? Sorry if this is a stupid question

To provide a useful answer, please post how the glow plug system is wired on your truck. Pictures help too!

The CUCVs didn't come from the factory with a pushbutton GP system. Your truck has been modified.

More than likely the PO wired the switch incorrectly. He probably is running ALL the power for the GPs thru the switch. You may want to redo the wiring job.

Only thing that you need is a push button switch for the coil ground wire on the GP relay on the firewall. The coil itself doesn't pull much power and shouldn't be pulling that much juice.

Have you downloaded the TMs and looked at the wiring diagrams for the GP system. If not do it so you will be familar with the concept. CUCVElectric.com has a great GP diagram.

Also in the CUCV stickies is a great video that fully explains how the stock system works.

Here is the GP diagram that I modified to show just how simple a pushbutton addition is. The switch can be attached anywhere along the light blue wire.

Make sure the switch you chose is capable of handling the load. The first one I chose was not.

This is the same one I used that works great:

Just connect the blue wire from the card to the switch, and then switch to ground.

I switch mine from the card, not the relay as shown above.

All the above is good, assuming your relay is still stock.

Grounding the blue wire with a different relay may result in GPs constantly on.

You need to identify what you have, or start over.

Bad advice. That switch is MASSIVE overkill. For this application, you shouldn't need anything more than a lightweight switch. A 10 amp switch is MORE than enough.

If you are burning out switches, you are doing it wrong.

It's NOT the fault of the switch.


Until you understand how it should be wired, and how it is wired now, you can't get to the cause of your problem.

I agree that proper wiring comes first and foremost, but for $3.50, I'll also take massive overkill. Kinda like the ring to it.

 

[MarcusOReallyus]

Nothing wrong with overkill, but there's everything wrong with thinking that a huge switch is needed. If you are burning out 10 amp switches, you are doing it wrong. Period.

Recommending a massive switch to correct a wiring problem is bad advice. Putting in a 60 amp switch isn't the right cure. Wiring it correctly is the right cure.


Nothing wrong with a 60 amp switch wired correctly.

I use a 10amp rocker switch (I had a bunch laying around) and it works fine as well. If you have the wrong kind of GP relay/solenoid on there this could be the problem. Take some pics of your relay and how the switch is wired! The relay is on the firewall next to the brake master cylinder.
