TL90 battery draining......................need help?

kingranchf350 · Jan 23, 2014

I have a 2004 NH TL 90 that has a problem with the battery draining over a period of 2-3 days. I have tried to find the drain but have had no luck. Has anyone experienced a similar problem or can anyone give me a idea on where to start? Thank you for any help.

As a temporary solution you could install a battery disconnect switch.
R.V. sellers would be one place to obtain one as many have dual battery installations and they like to isolate them.
I found some on EBay as well.

Disconnect a battery lead. Take a small 12v light, like an instrument light, and clip it from the batt terminal to the removed batt lead. It should light up cuz the leakage current will be going thru it. Now start removing fuses doing just one fuse at a time til the light goes out. Do the Ignition fuse last if you get that far.
