Battery charge repair

Got a project that you are working on that is not a tractor? Maybe a barn to hold your tractors or just fun stuff like woodworking, glass, tools, sheds, gardens, custom implements, etc., this is the place to talk about it.

Battery charge repair

Postby BOB K. » Fri Sep 08, 2017 6:44 pm

I have a Century #87151c battery charger that stop working. I see a lot of videos of people fixing the but not the one I have which looks different the others and all the wiring is soldered. Can anyone help to try and fix this before buying a new one?I am attaching photos of what I have. Thanks

Century #87151c battery charger wiring diagram and owner's manual are on line.

Print out the wiring diagram. Following the wiring diagram, I would start by testing the 120 V. line cord and battery cables. Then move along the diagram to the fuse. Everything good so far, check each switch and the meter. Then the transformer coil(s), lastly the rectifier bridge.

I have purchased non working battery chargers at auction for a dollar. With a multi-meter, the charger's problem is easily detected. Most times it's something easily repaired, like a bad 120 V or battery cable, or a bad switch.

Edit. Blew up the photos, again. There appears to be two circuit boards in photos 1 and 2. The soldering does not appear to be of factory quality.

If your testing didn't disclose a simple fix, I would junk the charger.
I have an excuse. CRS.

Eugene, did you find the wiring diagram for this charger? I have been looking with no luck.

I googled this: Century #87151c battery charger wiring diagram, and a bunch came up. Same with owner's manual.

I have found wiring diagrams for every other charger but non for the 87151c. I found for the 87151 which is different then the 87151C.

Without the exact wiring diagram you should be able to use your multi-meter to check the battery and AC power leads as well as the fuse, switches and meter. Depending on how the rectifier was constructed, you may be able to check it.

If the problem is not something simple and easily repaired with locally available parts, it's usually not worth the expense. From experience, when I needed a repair part, the part(s) were available, but cost as much or almost as much as a new tool.
