Default 1994 FLHTCU power surge

I need some help with my 94 Ultra. every time I use my turn signals or my brakes my volt meter bounces and my headlight dims down, does anybody have any clue on how to fix this problem.

Start out with checking the condition of the battery and the charging system, then clean as many connections and grounds as you can. Hope this helps.

Hi Josh and welcome to HDF from the UK.

If you still have these problems after checking things are OK as miacycles suggested, the most likely cause is an electrical short to ground. If things were OK until recently, have you disturbed anything, while servicing, or making changes? If so go back over your work and check for a pinched wire, or something rubbing where it shouldn't be. If not, look for a chafed or broken wire. You may need to be patient and persistent!

Let us know how you get on.
