It had both diodes on one board, and the factory setup had them on 2. The diode I bought was listed by the seller as fitting the model number of my charger. I found a troubleshooting guide that Lester published and used that to determine that it was a bad diode that blew the fuse, so I replaced both of them. It was ideal for that setup because it charged much faster than the Powerwise chargers. I have used this to charge the Black Beauty at the farm, so for the last 5 years it has charged using a generator. I was aware that it was the higher output that's the main reason I wanted to fix it. If you got the fuse and the diode assemblies for a regular Lestronic II, one or both of them may have blown the instant the charge came on and tried to charge the cart's batteries. Yours probably has diodes with higher amp capacity. The regular one puts out about 20A and yours puts out 36A, so the fuse assembly is 40A while the regular version uses a 30A assembly.Īlso noted the diode assemblies are different, Your charger uses a Part#16946S while the regular one uses a Part#16354S. Does anyone know where I can buy either, and any idea on the cost? Any other ideas of something else that could be wrong?ĭid some more looking and discovered your charger is the higher powered version of the Lestronic II. And even if I can find one, I'm afraid the cost will make it impractical to fix it. I found the diodes and fuse for sale on the internet easily, but I don't see a transformer or a capacitor for sale anywhere. My meter doesn't have clips, and I probably should have one to try to run those tests, but I am wondering if there is any point. It looks like that I must have either a bad transformer or a bad capacitor.
I left it plugged in for about 5 minutes and the AC cord was getting hot. I checked at the battery pack to be sure it wasn't putting out, and it wasn't. It comes on and hums, but it doesn't register any output. I replaced both diodes and put in a new fuse, but it wouldn't work. One link of the fuse was blown, and my testing showed a bad diode. This was a fine charger that would charge the cart much faster than the EZGO chargers I have, and I was disappointed when it suddenly wouldn't come on one day. My Lestronic II 36 volt charger has served me well for over 20 years, and it was used when I bought it.
