Eliminating intake heater

Postby DALEDOZER » Tue Feb 13, 2007 7:10 pm

I've been having problems with my intake heater, sure you guys heard it before, intake heater won't come on, alternator won't charge, WTS light won't go out and flickers. So I removed the relays, heater, spliced wires together at temp sensor on intake manifold, cleaned tach. harness along with a few others. Only when I start it, there is no charging from alternator until it gets warm, sometimes as long as a half hour then just starts charging. Once its warm you can shut it off and start up again and will charge. I would just like to bypass the intake heater all together, how do I do this?

Sounds like you have other issues, but I will tell you how to do away with the grid heater. Simply unplug the 4 small push-on wires at the grid heater relays on the d-side fenderwell.

Sounds like bad ground, pcm or crank sensor issues. I'm not the expert there though.

Sounds like a PCM, I've had 2 out of my 3 do it to me so far. They work fine when its warm, but cold forget about it.

Thats not a leak, its the external lubrication system.

Can the PCM be eliminated?

I think you'd have to convert your alternator to an external charging type along with a external voltage regulator. I'm no expert there though.

Dale:

I think that Bill is right about the charging system, the speedometer/odometer may be affected as well along with the factory tach, if so equiped. Other than those things I can't think of any thing else that it would affect.
