Not sure what happened. Will have to type all that again, sigh.
I have an E450 Super Duty cutaway with a starcraft shuttlebus body on it. 6.8L Gasoline engine 2003.
Anyway, I suspect there is something wrong with my wheelchair lift circuit. I replaced the 12.18 volt output obviously worn out 850 cold cranking amp car battery last night with a still has some life AGM 100 Amp Hour battery which read 12.72 volts after charging.
I was able to lower the wheelchair lift a couple hours ago, and was using it for seat removal. Then it wouldn't go back up. Thank God for the hand crank. The battery now reads 12.37 volts even with the engine running. (It was 12.72 at the time of install). I threw an exterior battery charger on the battery and it has a little meter on it showing 40% battery charge... so my guess is that the van isn't charging the battery right. Now I don't really care about the lift and it's coming out eventually but I wanted to use it for the seat removal, and now I'm worried that the auxiliary charging circuit isn't working properly. I wanted to make use of that circuit and the auxillary battery for "house" current, and charging off the alternator which I'm sure is how it is supposed to work.
Anyone have ideas? I'll provide an update as to whether the battery can make the lift go after it charges for a while with my exterior battery charger.
