I have decided that rigging the vacuum pump for the power brake system to the brake pedal switch isn't the best thing.
It works fine in regular light traffic, but if I am stuck at a light, or worse yet, on the yielding side of a busy intersection, I am stopped for too long with the pump running.
I imagine the pump pulls even more amps when it gets up to where it really can't pump anymore, which is right around 20.
I hadn't had any luck finding a good, cheap vacuum switch anywhere. Yesterday, I got to see a nice (high-budget) S10 conversion. His has a fancy 12V vacuum pump with a switch built right on it.
I took a digital still photo of the markings on that vac switch. I was able to find that particular switch through an on-line retailer. I just placed an order for it. $22!
I have not been too fond of paying for new anything on this car, but this should make the brake system really slick, and be good for a long time.
I also managed to stumble across a price for just the battery charger on that S10 - it costs MORE than my entire Geo Metro conversion!
