I have a 78 Shovelhead police special. A red warning light came on. I have no idea what it represents.. any help?

 

not 100% sure but i think it means your handle bars are to high.

 

only red light on my 1980 is oil pressure warning

 

Ditto on the oil pressure light. Stop driving it immediately until you check it out. First check to see that you have oil in the tank. Then check to see if oil is returning, remove the oil cap and filter and start the bike. You should see oil flowing back to the tank after a few seconds. If not, shut it down and check the oil pump for a sheared key or a missing snap ring that let the shaft move and drop the key. Let us know what you find and we will go from there.

 

FIRST - remove the wire from the oil sender switch to see if the light goes out. If it does, it could simply be a sender gone bad, they do that sometimes and aren't expensive to replace. If a new sender doesn't make it go out running slightly above idle (briefly), then follow steps in the above post# 4
