[Ronald R.]

Does anyone know the difference between a 1118825 and 1118826 voltage regulator? thanks Ronnie

Ron,
The 53-55 TIMJG on page 140 indicates the 825 is a 45 AMP for 53 and early 54, the 827 was for mid 54 and 55 6V, the 826 is a 30 AMP for 55 12V. Hope that helps.

That's a 725 in the judging guide, not a 825. 825 was the regulator the NCRS originally accepted for a 1955, 12V system. 825 and 826 amps are the same.

A little more thought and research might be required to answer this question. The 1118825 was a 30 amp. 12 volt regulator designed to replace: (1118749, 1118750, 1118826.) The 1118825 was used on:
Buick 1953 50, 70; 1954-55
Cadillac 1953-55
Chevrolet Pass 1955 w power steering/air cond.
Oldsmobile 1953-55
The 1118827 was a 45 amp 6 volt regulator and the dealer was instructed to use it if and when replacing the 6 volt 1118725

The 1118825 was not designed to replace 1118826. There are no 825 or 826 regulators dated 56. 55 Corvettes were using the 826 thru December of 55. The regulators are interchangeable

Ron, If you have no luck locating a regulator I have a 826A that I had rebuilt for a survivor car. (Base looks good, but wasn't replated).

Re: 1955 voltage regulator

I found a 825 dated L4, is that close?
thanks RDR

Good for a driver or a car that has already been judged. It will appear correct. If your car it being judged it is not within 6 months and not the 826 number that the judges look for.
