RE: F4 problems please help
Hint: Usually, the regulator burns the connectors when it goes bad.
Before you replace the regulator. Make sure you check the 3 yellow regulator inputs that come form the alternator. Let the bike run off the battery while you check this. If you don’t read the same voltage at each input find the bad connection. At about 5000 rpm my CBR 900 has 33-35 VAC between each yellow regulator input and ground.
Check the battery voltage with the regulator installed with the bike running and turnning 5000RPM. The voltage when the battery is charged should be exactly 13.5VDC. If it is under 13.5VDC there is probilby a problem somewhere. (When one of the wires between my regulator and alternator was bad I read 13.2VDC at the battery.)
If the voltage is ok at the battery and the voltage off the alternator is ok. Your regulator is probibly ok. Put some cpu grease between the frame and the regulator rectifier so more of the heat conducts to the frame.
It could be that your regulator is just to hot. When the regulator gets to hot your bike will run great for about 3 miles then sputter jirk quit and **** you off.
