Being more mathy would be a good thing, no?





Crayon eater.

Math is good, I'm just terrible at it.

Speaking of which, do you have any accumulated boost after your engine quits? Like how you can pump a vacuum system several times after killing the engine? I know that's how these units are supposed to operate, but none of mine do. If I hafta rip mine apart anyways, I will probably replace that accumulator while I'm in there.

Which vehicle of mine are you asking about?

 

[campfire]

Which vehicle of mine are you asking about?

Any vehicle you own with a GM hydroboost unit.

LOL, well that kind of narrows it down.

So your question, can I pump the brakes after I shut the truck off?

Yes. In all 3 of mine, the brake boost quits immediately when the pump stops spinning. According to the manual, I should be able to pump the brakes several times before the compressed gas charge in the accumulator runs out. So it should feel like a vacuum system, boost decreasing over the course of a few pumps of the pedal.

 

[GWeakland620]

Yes, I can pump my brakes to say, bleed the system.

You can always pump the brakes, but that doesn't mean that you have the booster helping you. You're supposed to have help after shutting off the engine. That's what I'm asking about.

You ever drive your truck without the P/S pump? It makes things all kinds of interesting.

 

[GWeakland620]

OH, then no. I don't believe the booster helps at all. IF it does, it bleeds off rather quickly.

Ok. Supposedly it's not supposed to be like that, but I have yet to meet one that isn't.

Hmmm, I did not know that.

It's like finding out in 8th grade that you are color blind...

I've heard a rumor that some folks can see infrared, we're both missing out on so much.

Please don't die, then who would listen to my stupid ramblings?

@F.S.F.W

I said listen to the ramblings, Aaron has a way of deflecting them that Greg hasn't yet mastered.

Hey! I'm not deflective...

 

[campfire]

That's exactly what I just said.

Go re-read my post.

Aaron, OTOH, is a deflective individual, comparatively.

So tonight I am going to attempt to properly wire up my efans. Need ideas on how to wire up the relay. @skunked @wheels87k5 @F.S.F.W any help?

Assume that I am on the same level as my 3yr old while doing this. I hate electrical.

 

[skunked]

red is the positive, black is the negative

 

[sreidmx]

Connect both to both posts on the battery.

 

[skunked]

let's start with how you want to control them. Are you running a manual switch and/or a temp switch? Do you want them both controlled by that switch or one manual or?
