RPM needle not working.

If the RPM needle stops working and just twitches is that a sign that the coil is going bad.?

or a poor connection on the front coil... I would check the connections first... but if you aren't getting any r/m then you are not getting spark to the front cylinder and need to find out why asap.

there is no cable for the tach on a vn750... or a vn700 for that matter. the tach is electrical... The signal for the tach comes from the front coil. I have a whole thread on this helping PoggiPj on this problem 2 years ago. we got very in depth on how the tach works and how to tell if it is the tack, a broken wire, or a bad coil.

Whoops! In the spirit of so many politicians, I misspoke. It was the speedo cable I replaced. Sorry, I wasn't playing attention.

SlimVulcan, could you post the link to that conversation w/ poppiJ. I can't find it.

My 1985 VN700 started having a no fire issue on the front cylinder yesterday. Initially the tachometer worked fine, but today, it worked for a few minutes, then I saw it go to zero and does not work at all since. A new tachometer will cost me about $250+, a new front coil about $80. Is there an easy way to tell which is faulty. I did the tachometer test in Clymer's talking about a bare wire connecting the brown connectors and quickly tapping another bare lead from the female end of the black wire to the brown lead, but the tachometer did not move. According to Clymer's that means the tachometer is faulty, but some other posts have said the tachometer won't work if it's a faulty coil. I have limited mechanical/electrical experience, but have removed cleaned and rebuilt the carbs twice due to a flooding issue, and they seem to work fine now. Just when I thought I'd be out riding for good, this new "issue" arises. Any help is greatly appreciated in advance.

You realize this post is almost 2 years old?

That took a little bit of digging... but I found it.

Speedometer & Tachometer not registering

start a new thread addressing your issues so we can document every thing you have tested and need to test for.

and this thread Front Cylinder will not fire, sounds more like your problem.
