1985 GL1200 LTD
At some point this weekend when I get off my lazy butt, I'm going to tear the front down again (just did timing belts last weekend) so I can troubleshoot my coolant temp gauge. I'm looking at the circuit (attached). I've never really looked much at these. Since my fuel level works, I can supposedly skip from the S198 point to ground. (page 114 of the electrical manual). Where I get lost is between there and all the way to the dash. I understand there's a green and black wire, but from where to where? What is C75 (6-Red). From there I can tell I'm following a green/blue wire from the sensor to the dash. Am I checking for resistance? Continuity?
