troubleshooting battery problem
Hi! I recently inherited a 1976 hi-lo trailer which has been sitting for about 5 years but was reportedly in good working order up until then. I don't know anything about trailers but am trying to see if I can get it functional. I've learned a ton from these forums but I'm stuck and hoping to get some advice.
The battery was dead, so I hooked it up to the car battery and raised the top. Then I replaced the battery with a new one and everything seemed to be working fine, and i also plugged it into shore power. Another day or two and I go to lower it and the battery is dead. Turns out the pin from the breakaway breaks had been removed and also the converter was tripped and wasn't working. I turned back on the converter and got a new pin, but the battery still wasn't working. I exchanged the battery for a new one, but it's still not giving any power to anything in the trailer including the lift, lights, etc. I cleaned the terminals. Still nothing. Any ideas on what the problem might be??
