1927 Buick relay

Has anyone seen one of these before? It is on the manifold and has two relays under the box. Two of the wires from the box go down below the vacuum advance linkage. I have not seen one in any of the pictures of other 27 Buicks.

The switch on the underside of the steering gear is you headlamp switch. The electrical box shown is probably a voltage limiter. This was a way to limit voltage before fuses and circuit breakers were used. My 29 Buick has one under the dash . All vehicle electrical current passes through it , except for starter motor draw, on my 29.

Certainly not a stock part, the combination ignition lighting switch already comes with a built in circuit breaker.

The relay are for reduce the current in the wires that goes thru the steering tub to the levers contacts.

I believe you are right, I traced the other end of the wire to the headlights. Thanks for the info.

I have not been able to find what the third lever on the steering wheel is for. Someone said it was a light switch, with what was said above I am guessing that it is?

The lever around the horn button is probably the selector between low and high beam.
