I have a 1998 Holiday Rambler Imperial. In this MH the tachometer gets a signal from the alternator to determine the engine RPM. When I bought this MH 3 years ago the tachometer was not working but the PO said I really didn't need it since it had an automatic transmission. I now know better so today I decided to determine wether the tack was bad or there was a problem with the wiring. To make a long story short, it's the wiring. To make sure I ran a temporary wire from the alternator directly to the tach and everything worked fine. So here's my question. Do I need to put on my Dick Tracy hat and find the break in the original wire or can I just run a new permanent wire directly connecting the alternator and tach.
