1928 Chrysler Generator Cutout Amperage?

[leomara]

The cutout for the generator was originally a Delco Remy but other 6 volt units can do the job.  However, there seems to be amperage differences in their construction.  What "capacity" for lack of a better term is correct?

What is the model number of your generator?

[leomara]

Delco Remy 949-L

I do not have the specs on that particular generator, but, the cutout used is a Delco 265B. It is the same cut out for many cars. See attached.

So what amperage is the 265-B rated for?  I found this on an old AACA post, but 0-3.0 AMPS, how can that be right?

Steve, the Delco cutout relays 265-B to V have the same specs. The 265-A & 265-W are different.

Specs for the 265-B to V :

Contact gap is .020"

Air gap is .015"

Cut-in volts 7.0-7.5

Cut-out amperes 0-3.0

[hwellens]

The 0-3.0 amps may be the rating to pull the contact down and not the rating for the generator output. There are different size wire windings.

My guess is that 3 amps is the minimum current let through by the relay. Experience with three different D-R relays and generators indicate that maximum output on the 28 era is around 16 amps, not much compared to maybe 35 amps on 10 years younger models. But it will suffice unless you do prolonged nighttime driving, then LED bulbs or a larger generator is needed.

Thank you.

Any amperage ratings/specs on a cutout relay are strictly referring to when they open and close. A cutout will not control the amperage output. Output is typically controlled by a 3rd brush on most generators from the cutout era.
