From: "bobnoffs" <icubob@gmail.com>


i am having a hard time sorting all the replies out, going in a lot of directions.
with what i have said couldnt i just jump across the solenoid while it [ the
solenoid]  is turned off and check the eis voltage? if it is back to 13.2 volts
i would know the problem is corroded contacts?

Bob,
Yes, you can jumper across the master contactor for testing purposes.
I suspect there is an indication problem, not a problem with the contactor.

thanks joe. i will try that as soon as temp gets above 15f.

 i have already checked voltage at the 'cig lighter' with my new uninstalled panel
voltmeter and my handheld voltmeter and they both read 12.6 like the eis while
both reading 13.2 at the battery.
  and there is only a foot of fat wire from the battery to the solenoid where the
voltage changes from 13.2 to 12.6

Does the (13.2 minus 12.6 = ) 0.6V voltage drop appear when you measure directly
across the solenoid?

Does it vary with load current - when you power the landing light, or radios?
