Electrical to Accessories Off and On

[jwdavies]

Just checking to see if anybody else has experienced electrical inconsistencies to their accessories. Earlier today the radio, lights, bilge, etc. weren't working but later on in the day they were working. Then later again not..... Any ideas? Tige 22VE

check your grounds under the dash might be loose, i have that same thing happen occasionally. also could be blown fuse if they dont go back on.

Could be a battery cable left loose by the same person that didnt drain your heater core during winterization. Do you have the Tige EIDB dual battery system? If so, could be a dead "house" battery.

Ok. No loose wires on the batteries or ground. I am wondering if the accessory battery is connected correctly. Would the primary battery support the accessories at high RPMs? It seems the accessories work while the boat is cruising but not sitting still. Is there a wiring diagram for me to compare to?

It turned out my accessory battery was dead and the accessories would work when the engine was running at full power. I guess that battery would get some charge during high rpms. New battery now and working fine. Who knew?

Thanks for the update! That information could help any one of us one day.
