Thanks Wildcat. That's me always over thinkings - trying to figure everything out before I start. How about getting codes due to the disconnected relay wires? Did you experience any?
Great write up on your install BTW.
Thanks,
John

My 1st Gen starts easily and reliably down into the teens with no grid heater. It takes more cranking the colder it gets, but will start reliably into the negative numbers with a shot of ether. Did it a couple times so far this winter around zero one day and -18 the other. No grids, just a shot of ether to reduce cranking time.

Hey John,

No codes.

You don't disconnect the solenoid coil wires, only the higher power contact wires.

After that, the only trick to "Code Free" starting is turning the key on, and immediately cranking the motor. This will prevent the computer from seeing the draw the Grid heater would normally cause.

I believe all this was in the previous thread, (Post #16 ) but here it is again for re-iteration...

Did your rig not have a ground wire connected to the heater block and intake manifold?

nope. no ground wire there.

K thanks.Thinkin grounding through the bolts or gaskets is'nt too good for as many amps the heater pulls.Have you ever heard of an explanation for why they did away with the ground wire?
