Blowing 12V Fuse......?

[C Rob]

Please excuse me for not doing a search first, but I'm using my cell phone for a modem, and it's pretty slow.

Last Saturday, I purchased a 2001 Starcraft Lone Star slide in. It is in near new condition, but the guy told me before hand that it was blowing the fuse. It blows it as soon as you plug in the 110V power and will blow it if changed while plugged in. With the fuse blown it will not recharge the on-board battery.

Before I spend the $$$ on a new converter, I would like to know if someone has had this problem or get some trouble shooting tips.

Thanks in Advance,

If your blowing the fuse for the battery charge disconnect the leads to batteries. Try new fuse if fuse holds would be the leads to battery.
Most likely the + side. With leads disconnected and fuse still blows maybe converter or some thing inside shorting to frame of converter. Loose screw, to long a wire or wire clipping.

My convertor has two 30A, 12V fuses to protect the convertor/charger if the battery leads are attached backwards. I'd first insure the house battery is good, then trace the battery wires and make sure the negative wire is going to ground. The positive wire should be red,BUT! It should also run to the convertor when traced.
When not hooked to 120VAC the 12V lights do not care if they are getting power from the positive contact or the negative pins, but the convertor/charger blows fuses when attached incorrectly.

Your right with that thought. Do your batteries light the lights 12V. Like you say a reversal to ground is going to pop that fuse.
Your wires to batteries could be black and white.
