Hey guys I have had my PJ dump trailer for probably 5-6 years and noticed the trickle charge that it's supposed to have is not quite working anymore and I've heard this has happened to a few people with PJ dumps. Place local to me that sells them says they have been installing basically a wire from the trailer to either the truck battery or alternator, I'm not really sure, so the trailer dumps off the truck. And they would charge me $500 to do it. Was wondering if anyone has done this or know what I should do? Is it as simple as hooking something to the battery terminals on the trailer and run them to a plug then hook wires to the battery on the truck and run that to a plug in the back then just plug into each other when I'm pulling the trailer? Any help would be great. Thanks guys.
