This charger appears to be " charging " but the fan won't kick in..
I put a CA inline with the charge wire and it does pump 4 amps ( 160w ) to the battery, but the fan never kicks in and i'm sure it's just a matter of time before it fries without the fan......
I pulled the fan and gave it 12v, it runs
Probed the board without the fan hooked up and i get 2.6v, let the charger run a couple minutes to let it warm up but the output voltage to the fan remains at 2.x volts.....
There are 2 fets on each side of the charger, on one side, the metal bar that screws and pulls the fets tight against the body of the charger was not tight at all ( cross threaded and the bar was just flopping around in there .. ) .. but the fet legs do not appear fried.. .. and the charger was functional for a whole season, this is the 2nd season on it.
any ideas ?
