Error Code Help Please

[VR4 WRC]

Hey,

I have pulled 2 codes from the dash by putting a paper clip in pins 1 & 4 on the OBDII port. They are:

Eng 64 FR Alternator System Terminal

AYC 41 TPS System (Short or Break)

Some background, volt's were low awhile ago, had these 2 codes. Had the alternator rebuilt with new brushes and rectifier. All good for a couple of week's. Noticed battery light on the other night when went to move the car.
Volt's with engine turned off: ~12.3v
Volt's with engine idling: ~11.7v
Volt's with engine fast idle: ~13.5v

I am trying to work out what's loading up the system at idle and where the system terminal is for the alternator.

Plugs on back of alternator seem good, belt tight no squeeling.

Thanks in advance

Scott

41 can be caused by low voltage (TPS error).... A lot of people who pull codes will see this one. Both my cars get it.

Check to make sure your battery terminals aren't stuffed (Especially negative).... Apart from that I have no idea
