Repairing A Wireless Towing Light Kit

[mrrz500]

I bought a cheap Harbor Freight (Yea, I know ) Wireless Towing light kit to tow my 1986 Suzuki Samurai behind my motor home...... I'm trying to keep the Samurai as stock as possible, so went the easy way with no drilling or cutting... Anyway, after about 6 uses one of the lights stopped working... Past warranty, but called them any way... There reply was to toss them in a trash can and buy new ones... Nope, they aren't getting anymore of my money for lights... The units are sealed, but I got the broken one apart and they have a 3-18650, 2000mAh, 3.7V battery pack in them... It is reading 4.1 V, which I assume is ok... I'm not good with electronics, but figured I could replace the battery pack... But that seems fine correct?... I hate to just chuck $130 out the window as they are like new, seem pretty well made and worked very good, until they didn't... Anybody ever have any dealings with these things?
Thanks, Butch

You probably junked the lights already. But the inductor in the L1 spot on the pc board is bad. I've torn a few apart and everyone was the same.

Thanks for the reply.. And you are correct in that they are junked…. I’m not great with electronics, so I probably couldn’t fix it anyway.. But it might have been fun to try.. Again, thanks…
