Basic High/low headlamp wiring question

You are turning on both filaments by running them that way. Yes they are bright together, but that will load up the headlight switch and smoke it out pretty fast.

The two outside pins have a common point which is the ground or center pin so applying power to one side and grounding the other side will light up both filaments.

Power to either side pin and ground in the middle, gets one filament at a time lit up.

Rotate the headlamp so that as you look at the back of it, the terminals appear in this orientation:

--b a| |c

For the 2A1 sealed beam, polarity is:

a, low beam feed b, high beam feed c, common/ground

For all other high/low sealed beams except 2E1, and for international H4, HB2/9003 and R2 bulbs, polarity is:

a, common/ground b, low beam feed c, high beam feed

No. There is no sealed beam that has the center pin as ground.

Hi Guys

thanks for the quick response!

And thanks for the asc art Daniel!

Another quck question...

In the dual filamament headlamp.....when it is being run on the high beam setting.....should BOTH the high beam and low beam filaments be on at the SAME time or JUST the high beam filament?

thanks again

take care

I just checked my auto repair info system- it only goes back to 1983 but it should be the same as your '82 (since it was the last year for the Spirit).

Anyway, my wiring diagram only shows the high and low positive feed wires (White and Light Green respectively) running out of a dimmer switch. On old cars the dimmer switch was seperate from the headlight switch, usually operated by foot or lefthand column stalk. I'm going to guess that yours is an "either / or" switch. This would mean that you get either 2 low beams or 4 high beams, never

I've seen different cars do headlights different ways but I'm willing to bet that your dimmer switch is just a toggle.

I guess I didn't describe that right. He sure sounds like he is firing up both filaments with whatever two pins he is hitting....
