Gixer1460 Posted September 20, 2022 Posted September 20, 2022 IMO a volt meter won't do much to indicate charging problems as a battery will show 12v till it's pretty terminal. My preference would be an ammeter as it will show discharge instantly or monitor charging and electrical usage. Quote
Andicog Posted October 4, 2022 Posted October 4, 2022 So would this problem cause the red wire from the alternator to get very hot at times? Mine has never cooked a battery and seems to charge fine but the red wire has been hot enough to melt its insulation, will this mod cure it or do I have some other problem? Quote
jonny1bump Posted October 4, 2022 Posted October 4, 2022 First thing do is follow what I've said and check voltage at battery, if really high that could be reason. Bare in mind wiring that old you probably got weak cable breaking down or bad connections causing high resistance, which would probably be best guess,but every bike different. They all old and depends on how well they been maintained. 1 Quote
jonny1bump Posted October 4, 2022 Posted October 4, 2022 If its melting insulation time to start serious maintenance and replace it. 2 Quote
Andicog Posted October 5, 2022 Posted October 5, 2022 Thanks guys , I'll dig a little deeper, stripping back some of the cables they're good so far, I expected the strands to be green or black with age but they're clean , would have been easier had I not wrapped the loom in self amalgamating tape some years back.....

wraith Posted October 24 Posted October 24 Going to be doing this over winter, as my charging voltage is reading 14.2 to 14.3v at 3000 rpm But can this be done with a bandit loom? With the bandit having the 6 wire ignition switch with the diode thing in it? Quote
jonny1bump Posted October 25 Posted October 25 Ignition switch feeds power on wire to alternator, its all same. All you need is switched positive to fire relay. Try just cleaning all connectors first and check you actually have voltage drop on this wire to alternator first. Dont go straight in without doing maintenance. 1 Quote

Compared to some others I've seen its about spot on, it'll keep battery well charged but not over-charged! 1 Quote

Think it's time for a new battery, it reads good but very quickly runs down when starting the bike. Starter motor seems fine to. Quote
