On my '87 Quad monopod the aux fan occasionally comes on and when it does the voltmeter drops to an indicated 10-11v. It also does it when I turn on the AC switch in the ****pit. I am beginning to think the aux fan is going bad and drawing too much power when it runs. Should I replace it? Comments?
I also noticed that the voltmeter in the dash was dropping below 12 volt when I turned the fan from the heating on on my 87QV.
Connecting a good multimeter directly to the battery reveiled that the onboard gauge is somewhat pessimistic and boardtension stayed well above 12,5 volt, check this first before relying on the onboard gauge
