Trouble after having spotlights installed.

A couple of weeks ago I had spotlights mounted on my bike. About 1 week later my netural light and gas gauge stopped working and then 5 days later it's ok. Now the electric fan suddenly started running (bike cold) and would not shut off till I pulled the fan electric connectors. Lucky I was near the bike and noticed this weird buzzing sound. Guess I need to take back to the shop and tell them to check their wiring. Anybody have a problem like this???

Maybe they ran the new wires in such a way that the original wires started rubbing on something and the original wires are shorting to ground. Seems unlikely that so many things could go wrong from a fairly straight forward wiring job though. When the switch for the radiator fan turns on, it closes and connects to ground. If the wire to the switch has rubbed through, the fan would stay on as long as the wire was touching the frame for instance. Or the switch may just be bad. I don't know for sure if the wires for the neutral light and gas gauge run through the headlight bucket, (a lot of things do) but if they do, the insulation could have rubbed off there. Might be worth pulling the headlight and seeing if anything's worn.

Do you know what they used for power and/or ground for the spotlights?

I would think they used the accessory leads in the headlight bucket if they're familiar with the 750 Vulcan. But they may have used something else which might effect the neutral light & gas gauge in some way.
The fan, on the other hand, has given others problems due to a bad connector or wires, so that might not have anything to do with the light install, especially with an '86 bike.

It is possible that all these sudden issues are coincidence, and just related to a 20+ year old bikes wore out wiring.
