David's 1996 Civic LX EV

Do you have an EV group in your area?

I'm guessing no, or you would have found someone to weld your rack already.

The reason I asked: I'm sure there would be members who would take your old pack off your hands at better than salvage rates. That's how I ended up getting the ForkenSwift's latest pack.

The closet EV group is about 2 hours away from me. I did get someone to weld my rack, but maybe I will check and see if anyone is interested but I don't intend to give up my old pack for core since it's not that old, about 1500 miles worth. But if someone would want it for some change, I wouldn't mind.

My US8VGC XC are in! Everything is set to go, but a do seem to have a problem with my power brakes. I noticed stopping was really hard, so I took a vacuum gauge to my setup and found it would max out at 15 inches of Hg. There was a lot of distance between the pump and my gauge, so I am wondering if the distance is throwing off the gauge?

I will do some adjusting tomorrow and see if it is any better. My pump is supposedly rated to 22 Hg max, so 15 Hg is pretty darn low, so I am hoping it's just the gauge being thrown off.

Hmmm.

My power brakes are set up so that the pump runs to about 20 inches. Anything above 10 or so seems to make the brakes run fine.

The connection between the vac pump and the guage is a few feet long, running through the firewall.

Is it possible there is some sort of a clog? Or something with the brakes unrelated to the vacuum?

There could be a clog, I will have too inspect the booster setup. There are no leaks because it will hold the vacuum for quite some time, but I have been told that the small tube I am using for the connection might be collapsing, causing the low readings. I am going to try a different, beefier tube and test it out again. Right now I am using a small, clear plastic tube that might only be rated to 14 or 15 PSI, so 20 Hg of vacuum might not work out so well.

I think my pump is coming on too late, like around 8Hg instead of something more useful, like 13-14 Hg.

If you have an adjustable vacuum switch, you might try setting that a little different and see if it makes any change.

I have tweaked it a bit, so now it comes on around 13-14 Hg and pumps up to 15+ Hg. The EV drives like a tank, weighing in at least 3,000 lbs, and it does stop, but I think I am going to upgrade my pump to a newer, more powerful, "quiet" one. I am getting use to it, and drove a total of 20 miles yesterday (4,6,10 miles with charging in between) to break in my batteries, and I may be able to commute in it again next week!

The clear plastic tube that came with my vacuum gauge now collapses at 15 psi. It still draws enough for the gauge to work (albeit a bit slowly), but I wouldn't trust it to pull vacuum for brakes. Have you checked to see if it's actually collapsing at any point along its length?

Woohoo - new batteries!

Why don't you advertise the used pack for sale? Post it on EM. I'd post it right in the Fossil Fuel Free forum rather than the general for sale forum.

And/or on the EV Album as well... I mean the EV trading post

I'll do that, post the used pack for sale here and the EV Album.
