Can't go over 2500 rpm's?

The TAN wire is spliced in the harness you just can’t see it, it connected back to the power packs to limit spark in the event there is a short (over heat, low oil etc) to protect the engine. If this wire is disconnected but still creating a ground it will continue to act like it should in this case limiting you to a low RPM, the other is the buzzer since you don't have a buzzer maybe just maybe this part of its function is working! My thoughts are to unplug the round connector and tone the tan wire out, single pin from the connector back to both ends of the TAN wires make sure it has no connection or fault to ground hope this makes some sense. Also it will not hurt to lubricate the round red plug connector when you unplug it. I really don't think it is your Stator period.
