My four year old batteries were not coming up to charge, I would see the
voltmeter reading 13 volts.

What condition did you measure this at? Engine off? Idle? 1500 RPM?

The problem is at idle everything seems to be great, but at
higher rpms the batteries discharge,

That seems a little backwards! Usually the charge rate at idle is very low
and comes up at higher RPMs.


I would take the alternator off and have it tested. Many auto part stores
have a setup for testing alternators and it only takes a couple of minutes.

If the alternator tests out OK then I would replace the regulator.
