I just replaced my sprag clutch on my 04 DS bajaX. I got it running after a jump and went to disconnect the cables and all was well untill i turned the lights on (it was late) and gave it some gas. the lights got really bright then turned blue and then just blew out. The the engine died. I then attempted to start it again only to find out i had no spark. CDI box was dead. I put in another CDI got it started and did some measurements and found that i was geting 18Vdc at the battery at idle. Does anyone have any ideas?

 

Troubleshoot the regulator/rectifier.

 

the battery was only at 10Vdc so im wondering if the rectifier is compensating for that. it is a aftermarket one.

 

If you blew your head lights go after the ground especialy if it blew the cdi i can almost guarenty it has a grounding issue.
