13.2V anywhere with the engine off is extremely suspicious. 12.6 sounds correct
for a topped-off lead acid battery, but youd have to be pulling some major current
to drop 0.6V across a solenoid, and if you were pulling any major current
from the battery it wouldnt be anywhere near 12.6V still less 13.2V.
Id recheck the 13.2V carefully.

voltage at eis is 12.6 with engine off. it is 14.3 with engine running. i have
checked all numbers with eis voltage, handheld voltmeter and panel mounted voltmeter
i just bought and they are all aligned.. measured voltage is 13.2 at battery
side of solenoid and 12.6 on the load side, engine off. alternator is charging
fine and battery voltage is fine but after the solenoid it drops to 12.6.
all this is with an earthx, not lead acid.
i haven't actually measured resistance in the solenoid but it seems to be pointing
at that, what else could it be?
