Ok, got around to load testing the 24v on my A0 this afternoon. 24v only feed to the cab with a blue sea amp meter and 100A shunt in that line.
ignition on 6A
start and idle still 6A. About the time the air tanks went over 66PSI and the buzzer stopped, it dropped to 3A. I dumped some air and reactivated the buzzer but the load stayed at 3A. There are 2 heaters, both temp activated, one on the primary filter and one on the air dryer. I no longer have one on my filter, so I suspect at 39deg, it was maybe cold enough to activate the dryer heater until it got enough hot air from the compressor to warm up the dryer enough to turn it off…
So idling, transmission in N N, and run solenoid, 3A. my gauges are now mechanical, i suspect a normal A0 would probably pull another half amp for gauges
Dryer heater 3A, I suspect the fuel bowl would also pull ~3A when active due to cold.
24-12 converter on, no change
neutral to D or R, no change
all my LED lights on +5.6A@24v, about 1/3 of what incandescents would pull. It will probably be close to 6A when all the habitat markers are installed
High beam +1.5A.
blower on high +7.4A
Wiper on high +2.1A
A little higher than I figured, and forgot all about the heaters, but Now we know…
