Ok I don't know why! Why would you want to turn off the grid heater in the manifold. I see people posting about it!

Yeah there is like 5 threads about it now :lmao:Anyways, I did it because the truck will run the grids if you turn it off, run into the store, run back out and start it. The grids draw 95 to 190Amps which is quite a load on your alternator and batteries. So I threw the switch in there to keep it from turning on when I know the engine is already hot. 24V's will throw a code if you switch the grid relays so all you can do is take the leads going to the grid heater off. I will make a big article for this right now for the static pages I can link everyone to. Think we got a lot of information drug out between 5 threads.

I like the idea of , on/off/auto. I am sure off and auto are what I would normally use, but it would be nice to turn it on with a switch if ever needed... But 99.9% of the time it would live in Auto.

Alright guys, got the writeup done and up on the static pages. I'd like to find out a way to do it on the 24V's but I need a 24V first So don't hold your breath for a 24V writeup, but maybe someday I will get my hands on one.
