eratic tachometer on winnebago cat c7 engine

[jr.]

Hi the tach on my 04 Journy go to zero the jump back up again. this has happened about 4 or five time in the last 50 miles I drove it I called cat and they did not think it was the sensor on the enging. If it was they said the check engine light would come on. I called freightliner and they said to bring it in and the would check cost 125.00 per hr. And if it need a new head that cost would be 370.00. Is there a way to find out the problem and if it is the tach assemble do you know of some place to get it. It doesn't look that hard to change. thanks in advance. jr.

I would suspect that it is more likely a loose wiring connection. Of course, tracing it might be a real pain. I have not had good luck with RV dealers' shops being good at electrical things.

You can download a full electrical diagram of your coach from the Winnebago website, if you wish to try to tackle it yourself. And at $125/hr, I think I would at least give it a go.

My shop charged me $150 to tell me that my turn signal problem was a Freightliner issue. I fixed it in less than 15 minutes (including troubleshooting) by plugging in a loose connector!!

I have an '04 Journey ... my fuel gauge was behaving erratically ...

Someone suggested I tighten the ignition switch ... I did ... the fuel gauge has behaved normally since then ...

I cut a small block of wood ... stuck it in the recess and used a screwdriver to turn the chrome faceplate a little ...

The fuel gauge has been behaving better...

Thanks for the info. I went out this afternoon and check all the connection for the tackometer and took off the cable and clean it with contact cleaner. Nothing seemed lose. So I will drive it till is stop again. thanks IF there are more hints let know jr.

Skigramp...found your reply interesting on the erratic fuel guage...My 02 Journey fuel guage slowly moves from full to mpty and back and forth..it reads about 1/4 less when staying stable...I don't understand what the wood does in tightning the cowl of the ignition switch....thanks RKL
