Batteries

Not powerstroke related. But does anyone know how many volts you should have in a 36v system. i have three batteries wired in series and im getting 42 volts with an ome metre. Is that about right or is it high?

I think I found your problem, try using a volt meter. Ohms are for measuring resistance.

Could be a coupple of things. First, check the batteries in your meter, low batteries can cause weird readings. Second, it's normal to see a bit higher than normal voltage with no load, but 42 is pushing it a bit. 42v would be about right if your charging the system when measuring it.

Considering moat 12v batteries put out about 14 volts, yeah, it sounds right.

If your 12v battery is putting out 14v, it's either overcharged, has an extra cell or an extremely high surface charge. 12v is nominal for a 12v battery, but the surface charge on a battery in good shape should still be under ~12.6v. You have to measure the voltage with a load to get a true reading.
