I have a Tier2 TriPac that shows a battery fault when I try to start it. The circuit breaker is reset it does all of the prestart functions, but it does not crank the engine. I disconnected the power to the unit and checked those connections, but it still will not start. I have not taken ant panels off yet, but I am just wondering what I should be looking for when I do.

I’m not familiar with that model, but on the first gen it has a 50amp fuse in the back by the starter. They were bad to shake loose and melt the fuse holder.
I think they started using a fusible link. It may be blown.A5¢ Thanks this. -
Thank you! That's a starting point and I appreciate the opinion of those who have worked on them.

To show my lack of experience with this critter, where is the 8s wire? I have done the maintenance on this unit, but I am unfamiliar with the wiring.

Thank you! I will open it up tomorrow and see what I can find. I will report back.

I opened up the panel and found the 8s wire. I had all of the buttons in the on position, just like normal and nothing happened. I did a voltage check at the control box, using the panel ground and only had 10 volts at the 2 and 2a terminals. I will remove all of the battery cables and do a draw test and see if I have a battery going bad.

I will have a look at it when I get a chance. I have firewood to cut for our Trappers Association, this coming week, so the APU will have to wait. I will report on my progress.
Thank you guys for the help.
