Hyster H70FT

H70FT s/n L177B09220D has intermittant battery drain, sometimes it will be good for days and then it drains the battery overnight. Have tried 2 different new batteries. When testing for battery drain with test light between ground post and cable end the light will stay on dimmly forever and the next time only for 30 seconds to a minute. No codes or other problems noticed. Any ideas?
Thanks, Darren

The VSM on this truck has a timer circuit that can stay on as little as 30 seconds and as long as 1 hour. It sounds like you have a diode issue in the alternator. You can check it like checking the battery with no meters, just remove the wires when you shut the truck down and see if the battery goes dead. You might have an issue with the power distribution module, or the wiring harness where it goes under the battery.
