[DML] Re: Fuel Pump Not Getting Voltage After RPM Relay Replaced

["content22207" <brobertson@xxxxxxxxxxxx>]

Hmmm, is that what those ignition resistors are doing on the firewall...

I think the point David is trying to make is that a poor connection
will increase resistance, which will generate heat, which will lead to
things like melted plastic, loosened solder, IC damage, etc.

Just touch a resistor with juice flowing through it if you want to see
what kind of mischief resistance can cause.

You are correct about the wiring schematic. Jim is going to need to
start at either end of the circuit and ring it out. That's really the
only way to find an electrical problem. Sometimes you can get lucky
and find the problem in the middle, but more often than not its a
linear process of checking for juice at each connection along the way.
The trick on a DeLorean is finding a good ground.
