voltage regulator

I have a 200 Amp altinator with an adujustable remote mounted regulator Type number - R0015016 RC, Volts - 14, Date Code -74-41,

I am having voltage fluactions of about 3-4 volts. It used to just be at idle, but is not at all RPM and with different loads. The cables have been cleaned and same problem. Is there a way to confirm if it is the altinator or the regulator?

Thank you for your help

Is it possible to provide ignition excite feature to 8mr2401ua?


I recently installed a prestolite 8mr2401ua self excite alternator, wired to the (+) Battery common post & the (-) Ground Buss via 4AWG cables as recommended. It seems to perform flawlessly in my initial tests. However, I noted that I need to rev my engine to get the unit to cut in. Although this is expected behavior for this type of installation, I would prefer to have the unit energized with the ignition circuit so if I forget to rev the motor at start up on my way out or in, the alternator will have cut in at idle cruising speed.

My question is two fold:

1) Is it possible to convert this unit to ignition excite? If so how is this accomplished?

2) Are there any dis-advantages to ignition-excite wiring method?

Thanks in advance.
