I have a 1995 620 R/XC and have ridden it for about 5,000 miles. When I first got the bike the voltage regulator was shot as it blew all the bulbs. I bit the bullet and laid down $200 at the local KTM shop for the official voltage regulator. Next I replaced all of the bulbs. Headlight works great but nothing else works. Just to get to the back country I've wired a hot lead to the taillight and brake light. I have no power to the horn, turn signals and any speedometer back lighting. The yellow turn indicator light occasionally comes on. I've checked the main ground and used electrical contact cleaner on all of the main harness loop contacts - no luck. I've replaced the turn signal relay not with a KTM one but one the NAPA guy swears is the same thing -no luck. It has been "upgraded" with a bigger motorcycle battery with one in-line fuse, which I've checked. I even put a new battery in to the tune of $50.00. I'm going broke trying to guess a fix. Any direction would be appreciated. I've run out of guesses. The bike runs great otherwise.
