I have a 1992 Rascal, Model 240. The charger assembly has a burnt mark on it. Is there a schematic or picture of the board that I can get? My brother may be able to fix it, but he can't identif
The charger is a 24v 4 amp one stage device. Its an incredibly cheap charger. It consists of a step down transformer, a bridge rectifier, a filer capacitor, and a voltage regulator. Virtually all chargers are made this way. Generic schematics http://www.simple-electronics.com/2011/10/24v-battery-charger-simple-and.htmlThis charger is built around the famous an popular LM317 chip it really simplifies things.http://www.circuitstoday.com/24v-lead-acid-battery-charger-circuI would get out my trusty multimeter and chase 24v though the device.You may need a VOM meter only $9

There used to be a time when you could order your your TV as a kit. You could literally teach your kids something useful at the kitchen table. Quite frankly a 2 amp charger cost $14 4 amp cost $28. Not worth fixing really.Chargers can be found here http://www.amazon.com/Electric-Scooter-Battery-Charger-Prong/dp/B001GMTKN4
