Have a g1 quit firing had a blown netural fuse replaced still not firing replaced the cdi with a used ran for 30 secs.blowed the cdi unit.Installed a new cdi unit checked was firing hooked to spark plug ran 35 to 30 sec blowed the new cdi need some advice what would make the cdi unit blow.someone had put a new ign coil on it is not near as big as the original.They also have put on a new starter generator do not know if anything wrong with either of them would cause cdi to blow.

If the ignition coil is pulling too much current, it should blow a fuse. Did you put a 10 amp fuse in it? Both fuses should be 10 amp to protect the devices.
If you can get a stock coil, install that. The resistance of the coil you have now is probably outside the specs and drawing too much current. Also make sure that the ignition wiring is correct, with nothing extra added to it.

Get a diagram from the sticky section above and check that the wiring is correct.

I suggest, you remove the passangerside fan shrouding,and the CDI Magneto assy and check for shorted pulsar or source coil or ground wire shorted ground wire. Also check to see if the 4 wire leads (off the CDI assy) are shorting to the frame. Good luck

Cart Runs ok without the use in it but does not charge has a new starter gen on it and it checks ok

Is the record for longest response to a post? 6+ years?

As far as your charging issue as you have a new starter / gen I would suspect that that voltage regulator is bad. Some of those VRs are adjustable and other are not. Do a forum search for how to tell. Those have been talked about a lot.
