Re: [A/S] Dodge Ram 7 Pin Connector
Jim,
You'd need a normally open pressure switch for that, wouldn't you? I
use that trick to energize the alternator on Diesel engines that use a
Bowden Wire shutoff (no key switch), and I always have a heckuva time
finding such an animal. Most are N.C., to energize the dash idiot light
when there's no pressure.
Using the ACC line for the relay/solenoid coil prevents it coming in
until after you've started the engine, as that line is usually dead
during cranking. You're right about specifying Continous Duty for the
relay/solenoid, not all are rated that way.
