Tachometer/Alternator Wiring

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.

Just an idea as I had a similar problem with an erratic PAC brake working. Follow the tach wire from the alternator as far as you can. Usually the end wire attaches to the main wiring harness somewhere close to where it terminates and see if that is bad meaning the splice or connection. Another idea is if it's easy enough, run new wire yes. Also google a thing called a power probe or look on amazon. The deluxe kit has a transmitter and detector for tracing wiring shorts. It will detect the signal through wire shrouds etc. and you just run the detector along the wiring run and it will detect where the break or short is. I have one and love it for this reason. It is also an amazing tool for diagnosing all other problems. Everyone should have one.
