Stumped! Wiring Issue 82 KZ750 csr..

OK, ya that's the accessory ground, for extra equipment such as grip heaters. Anyway you can see where the Black/ Yellow at the negative battery terminal is connected? This is the same, ends up going to ground at the motor block, but the open bullet connector shown in the diagram I would add a ring terminal and bolt to the frame. Your wire from the R/R if hooked into the Black/Yellow, Grounded, causes a spark/ short. You have defective diodes in the R/R.

Some choices for a new regulator/rectifier:

Alright that gives me a lot to work with..just miss my daily rider to death. Without her running Im half the man I was hehe. Appreciate it Motor!

Problem is I have other grounds male & female without homes..so maybe without those grounded the r/r wont work properly. Ill find out when I dig in tomorrow. Thanks again Mfolks!

The ignition coil "charges" while its primary winding is grounded.

Becoming ungrounded causes the coil to "fire" through the secondary loop.

In a points system, the primary winding grounds and ungrounds through the points.

With the igniter system, the primary winding grounds and ungrounds through the igniter, which reaches ground through a black-yellow wire.

It's important that the black-yellow wire provides a good ground from the igniter.

If the black-yellow wire fails to provide a good ground from the igniter, the ignition coil can't "charge."


Good Fortune!

Good info there..youre the man Patton
