Inoperative Fuel gauge/noisy Tach

Postby HondaWalt » Mon Jan 11, 2010 3:28 pm



Hi to everyone!
New Old guy to this site....
Just purchased a 1980 GL1100 with 27K miles on it, the machine runs good except for 2 things....the Fuel Gauge does not work and when the machine is running a whining noise sound comes from the Tach (discovered if I grasp the Tach and pre-load it a little the whining noise sound goes away?).
Prior to purchase I was told the gauge didn't work so it was an existing problem even to the seller when they had bought it...but the tach noise is new.
Since this bike has been a runner and not in cold storage for years I thought the fix might be simple so here I am in the hopes for advice to a fix...I did read about the 7 volt regulator replacements for the gauges but the symptoms are not the same... the temp gauge does work through it's full range.

Thanks! HondaWalt

If the temp gauge is working, then for sure it's not your 7 volt regulator. A lot of times it's just the connection at the fuel sender. It's right under the seat - try removing, cleaning and reconnecting the connector on the fuel sender. If that doesn't work, you can test the fuel sender to see if it is working correctly - the procedure is detailed in the service manual that you can download here from the manuals page.

Oh, as for the tach - you can try unscrewing the cable from the back of the tach and putting some cable lube down into the cable and see if that makes any difference.
