What do I need to know to fix an electric mower?
Mine won't hold a charge and none of the shops in town say they can work with it. :wtf: the problem must be in the battery and/or the charger -- how hard could this be?
I opened it up to take a look at it and it appears they just have 2 12v batteries wired in series. However, there are more wires than I would expect. There is stuff for charging, safety, and controls and it is not totally clear to me what does what.
I tried wiring the batteries directly to the motor and while it spins it acts like it's only on half voltage. Also, I get a good spark, so I presume I'm doing something wrong (I take it the normal switch uses some sort of relay?)
Anyway, I don't really know what I'm doing. What do I need to know if all I want to be able to do is charge the batteries and run the mower? I couldn't care less if I have to modify it so that it doesn't work exactly the same way as it does now.
