My first post on here. Thank you all in advance. I don't know yamaha sleds at all. I recently acquired a 79 440 exciter. Every bulb was burned out. Put a new taillight bulb in and it popped within 5 seconds. I'm thinking it's the voltage regulator. (As the taillight was extremely bright until it popped). I would like to know where that regulator is located. It's like playing cat and mouse with me. Any help is appreciated.
