Alternator wire melting
Posted: Thu Jun 18, 2015 7:35 pm
Hello all,
Long and short of it is the bike had little use since last oct. I fitted the carbs back and went to work on the bike yesterday. Within minutes I could smell smoke and the 3 yellow wires coming from the alternator were melting at the connection. I have fitted new wire and made good connections. The battey is not getting charged as the volts dont raise above 12v. I followed youtube guides and tested the mosfet R/R and that checked out fine.
1. I have traced the 3 yellow wires going back to the alternator. I want to check that all 3 wires are connected properly. When I was refitting the carbs alot of pressure was places on the airbox which may have crushed/servered one of the 3 yellow wires. Can I use a multimeter to check if these wires are ok? If so what settings to use and what should the reading be?
2. This could also be a possible cause. Im not 100% sure I have the ignition coils connected correctly. The only guide I could find was a guide for a 250 hornet. How can I find out the correct connections for my cb400 super four NC31? If these are connected wrong could this cause my alternator wire overheating problem?
