birdshill123 Posted August 9, 2022 Share Posted August 9, 2022 We did not use our unit during the pandemic. It was in storage . When the border opened we left for Mexico without doing some required repairs. While in Mexico health issues prevented me from repairing an issue with battery charging. But without the generator Alladin was showing a discharge on the house batteries. Usually around 20 amps. I knew the Bigboy relay needed attention. I replaced the relay about 9 years ago . I rebuilt the spare and installed yesterday. Same problem but the discharge is 6 amps. I let the engine run for around 15 minutes and nothing changed. Voltage on both sides of the big boy . Voltage at the 2 small relays. On the 08 Dynasty Monaco used an electronic board to control the charging. It is an Intellitec "B.I.R.D but an open board. Before I replaced the original Bigboy years ago I installed a new board. I did some checking yesterday and here is what I found. Engine running: chassis batteries 13.8 volt on Alladin, House batteries 12.5 volts 6 amp discharge. If I hit the battery boost the house batteries show a charge of about 35 amps The Intellitec board shows the following: Green light marked " battery disconnect on" is not lit Green light marked "battery disconnect off" is not lit Green light marked "Iso relay on" is not lit Red light marked " 7.5 amp pcb power" is lit Red light marked "7.5 amp battery dom" is lit At the bottom of the board there are 2 lights The yellow light marked " Battery disconnect switch" is not lit The green light is marked on the circuit board. States" ISOL lockout". It is lit. I have the original Intellitec board. It may be OK . I have not tried replacing the board but wonder if something else is causing my problem. Any help appreciated.
