isolator or bird?

Having trouble with house battery charging with altenator. Found 12 volts on solenoid coil after starting engine (couple min.) but isolator relay not closing. Ordered and replaced BIG BOY and now after starting engine am not seeing 12vdc on coil from bird.... Wondering if bird won't close for other reason than delay or low volts.? Have altenator putting out 13.8 vdc. No problem charging on shore or genset. Don't want to just throw parts at this one.. Any help? RFS

Well, the Big Bird is the most expensive part. You really need to get the wiring diagram. On mine it turned out to be a $6 relay that was part of the cross wiring, and I only found it from the wiring diagram.

Did you/do you have 12v going into the Big Boy control wire - by that I mean the small wire going into the side of it, not the two main leads?

If you had any charging voltage such as shoreline or solar during the solenoid change you may have blown a fuse. Measure voltage on both small terminals. If you have voltage on both then the ground side did not get connected well.
