Click & Charge Amps drop

Good Morning...

Been fighting converter issues for a while... well.. I think I finally figured something out.

When by converter fires up and goes into bulk charge it ramps up to around 46amps... within 30seconds I click is heard from the battery bank and the amps immediately drop to 30. If I shut off the converter and wait about 5min I'll hear the loud click again from the battery bank and then If I turn the converter back on I'll get 46+ amps again.

Any idea what could be clicking? Its a loud click like the noise made from the main battery disconnect.

It does this with that main battery disconnect on or off.

If I follow the + battery cable from the batteries it goes to the main battery disconnect & also goes to what appears to be a solenoid or something.

So I am thinking it has something to do with that solenoid. What would it be doing to draw the charge amps down by 10?

Is that solenoid there to sent voltage to the engine battery?

THanks, Jeremy

  • That is a case grounded relay. The two large posts are the feed and load.
    It could be the charge relay and auxiliary start relay.
    The circuit breaker would have two posts and be able 0ne inch cube. Could be metal or plastic.
    Do you have a switch on the dash that says AUX on it?
    This is on your signature Storm?
  • The diagram for the wiring shows a continuous use solenoid and a 50amp breaker in there. Doesn't look like a breaker to me as it has 3 posts. 2 have large wires on them and 1 has 3 tiny gauge wires on it.
  • It could be an auto resetting circuit breaker that is clicking. It maybe a 40 amp unit and the 46 is tripping it.
    If in fact it is from large relay, the voltage could drop enough to shut if off until main battery is fully or close to fully charged.
    Make and model of rig?
