Headlight and Tail lights Blew out

This is on my 1978 kz200


I started my kz200 the other night but forgot my positive on my Battery was loose. It caused the headlight and tail lamp to pop. 2 new bulbs and a correctly tightend battery everything seems fine.


Is there actually something wrong with the electrical system or does the battery need to be in place to act as a buffer?

The battery acts like a surge tank absorbing the excess power from the charging system. On the bigger 4's, the alternator runs wide open with the regulator/rectifier controlling the charge going to the battery.

On your bike the turn signal bulbs could have been popped along with any instrument lighting too.

It's a good idea to once in a while check the tightness of the many and various fasteners on your bike. Motorcycles create many frequencies and magnitudes of vibration.

I guess this bike is differant than my early Yammys they dont care if they have a battery or not.


Definetly will need to go over everything on the bike like you said.
