At the risk of repeating Robert, make sure your ground terminals are clean and tight. You have one in the front at the voltage regulator and one at the back on the support for the gas tank fill tube. If those are good and you've already done my first suggestion, I'd pull every bulb out and take readings with a meter on all the socket terminals. With the headlights on, you should have power on only one of the two terminals in each socket. With headlights off, you should have power on the other terminal and only the other terminal. This will tell you if you have a short in the wiring or a problem with the TS or Light switch. Get back to either Robert or I with your results and we'll go further. I hate throwing a $100 bill at a car and hoping it fixes it, so I eliminate everything else before buying parts. :wink: By the way, if everything else fails, it probably is the turn signal switch. Does it feel like it engages positively when you select a position or does it kind of flop around and feel loose?
