Talk Morgan Forums Morgan Sports Cars Morgan Three Wheeler & Super 3 Belt slipage whistle from Front

with a faulty rectifier, once voltage drops to low, engine stops and it is finished. With alternator issue, the engine stops because voltage gets too low but you will be able to restart the motor a day later at least in my case.

Rectifier issue i have had too in my long list of incidents..

If it's coming from the front, there are no belts to slip,if it did, you wouldn't be running.

But sometimes a slight exhaust leak can sound very much like a chirping belt.

I would check the exhaust flanges for tightness.

You can also use a piece of rubber or plastic hose, say 1/2" diameter and put one end at your ear and use the other to probe around the motor for leaks. This hose trick works very well for leaks.

Good luck in finding your noise.
