ZD326 charging circuit problems.

[Hfrs7]

While cutting with my ZD326 I noticed the battery light came on. When I investigated I found the connector at the voltage regulator was burned and melted. I replaced the harness connector and installed a new regulator. The dynamo was putting out proper voltage but nothing to the battery. I found the 15 amp fuse blown for the charging system. Replaced and blew again. Disconnected the regulator and it stopped blowing fuses And I was getting battery voltage from the switch. With engine running I reconnected the regulator and it’s been working since.
any ideas??

regulator failed.

I know but why did it blow the fuse after it was replaced? Then started working normally.

The wiring was overloaded with current from the first time it blew. When you replaced the first fuse, the rush of overloaded current overwhelmed the fuse, blowing it again.

Also check the polarity of the battery connections.

All good…. The situation resolved itself ….
