Disable pre-heating?

[jblueridge]

At first I thought my alternator was messed up but since the major electric drain goes away after a while, I think it's my pre-ignition heating system going crazy.

What's the best way to disable it? Thanks.

It is probably fed power from a dedicated fusible link, you could just disconnect that. Alternately, you could unplug the glow relay.

install a Wilson Switch?
