Powerwise Battery Charger Only Charges at 5 Amps

My neighbor has an older 36v series E-Z-GO TXT that wasn't running right. That problem was just a couple loose connections. The problem now is his Powerwise battery charger doesn't work properly and I can't find the problem. It only charges at 5 amps and I've checked everything that I know or can find. Everything seems fine and I hate to start throwing parts at it. Relay clicks [ jumping it doesn't help], diodes check good, continuity thru all wires/connections, capacitor reading is 1.7.

I basically know nothing about ezgo Is there a capacitor in the charger if so replace it if you have a schematic post it and I’ll take a look the capacitor will give a low-voltage and inturn a low charging amperage You need to check voltage when charging put your meter on the battery pack and plug the charger back in and give me the voltage

OK, I'll have to go to his house and try that. His charger acted the same on my cart. Everything I know to check, checked fine. I hate to throw a circuit board at it just for the heck of it especially since the relay clicks. Everyone says 99.99% of the time with these chargers its the circuit board [ which contains the relay and its the relay that fails]. The capacitor specs are 1.3-1.7 and it consistently reads 1.7. Because the charger does at least turn on and charge at 5 amps my thought was kinda sorta the capacitor too, but it checked OK. Thanks for the response.

It could also be a bad diode there should be two on the circuit board. They will look like large black resistors if one were bad you would get low voltage also

That was my first thought. When they both checked good my thoughts then turned toward the capacitor. I was so certain one was bad I took both off and checked them individually when they checked good together. I'm thinking about a 'rebuild kit' that contains the circuit board, capacitor and diodes. Throwing parts at something just goes against the grain though.
