Horn moves speedo

I finally got my exile setup all tuned without any interference thanks to Brian. The biggest interference I had before was the horn playing through the speakers. That is all remedied now but when selecting the horn the speedo will register as high as 40 (only with boat running or key on). I have not had it on the water yet to try it out. I never used the horn before just more curious if nothing else.

Well I feel silly now..

Never seen that one, my speedo goes wild sometimes when my 12" exile sub hits under the helm.

Speedo is Electrical so you might have a grounding issue.

Ground..........

Mine does the same thing.
