When I test at the wire soldered to the solenoid (with the plastic cap
removed so I can get to it) that is when it is "clogged up" and the
meter reads in the hundredths of volts not 12.75.
Others have said I have amps issue not a voltage issue and the relay
will do that if the contacts get burnt. That may be the source of the
high resistance.
Can I test the relay by running a lead from the brown wire directly to
the yellow purple at the relay and bypass the relay without messing
something up?
