Alternators

8RG2043 REGUATOR PROBLEM

I have a 8rg2043 regulator where the adjustment screw spins with no effect on the alternator output voltage which is low at 12.6 volts.

1. How do I force the alternator (model 8mr2069ta) to full output to ensure that the alternator itself is OK since the field terminal is behind the regulator?

2. Is that regulator available for sale as a replacement part?

Thanks

Technical Enquiry about Regulator

Hi,

 

I have a 8LHA2070VB Alternator (AMPS140 VOLTS12) with a 8RG2112 Regulator Attached (AMPS7 VOLTS12).

 

1. Is this a current and voltage regulator (i.e. continously outputs 7 Amps at 12 Volts)
2. Does the alternator curve reflect the output of the alternator or the output of the regulator?
3. What current is required from the alternator to get full current and voltage from the regulator?

 

Ultimately I want to know how many rpm I need on the alternator to get full current and voltage from the regulator.

 

Regards,
Li-Wen.

Alternator - Catalina 27

Dear sirs,

I have a Catalina 27 with an 11HP Universal Atomic Diesel engine with this alternator in it. I cannot find a model number on the back. Everything on the back has been rubbed off over the years. I had it tested at a local auto shop and it is only putting out 11 volts. They really guessed on a cross-over number. I did find these numbers but they may not be correct because everything was really faint.

846 (?);

51 amps ( for certain);

12V ( for certain);

110-389 (?).

 

Can you tell from the photos which unit I have?

Prestolite alternator AVI 110AMP,#35215335UK

1]How many poles does this alternator have[ie pulses per rotation]?
2]Do you have a performance curve for 50deg.C?,or how do I best interpolate from the curves you provide at 23.5deg.C
Thanks,

DUVAC sense wire jb2824

Hello....I have had a surging voltage on my dash gauge between 14 up to 15.or sixteen amps, it pulses at a steady up-down pace...reading some of the post here it seems it might be the "remote sense wire" if I want to replace this wire where do I connect the other end ? (can I just wire it to the the Pos. batt. term.?) hard to trace this wire since its in a bundle and I can't trace it......hope this makes sense....

 

thanks for any help
