I recently purchased a 1990 blaster! I took it out with a friend on Houghton lake through lots of snow and slush. the head lights were working all day. All of a sudden (of course when the sun was setting) The headlight and tail light simultaneously go out. They also happen to go out on my friends 2000 blaster. They have not worked on either machine since. I have replaced the rectifier on mine and still no sign. I only checked headlight bulb and the filament seemed okay! What do you guys think? Couldn't really find an answer browsing! Thank you!
