2006 Yamaha FJR1300 - KrZy8

Broke down no charge hiway 1 ride with Barries Boyz.

Has happened before https://candybuttorg.ipage.com/cba/node/520

I used the shotgun approach and cleaned battery terminals (already squeaky clean (asc)), battery to engine ground (asc), replaced 50 amp circuit breker from regulator output with 60 amp fuse. Charging is back!

Found the Smoking Gun

Circuit breaker at battery from regulator output.

And this bike is never power washed, runs in dry, not wet country. CB not sealed..

And this relay for fan cooling was bad too.

Just for info

Voltmeter - 45 mA
Rectifier/Reg - 26 uA
All - 46 mA

39 amps measured RR output to battery wire, full load
