Does the Civic VX have a unique alternator?

[molecule]

so then this optimization isn't just for the vx...
they all use it...
they wouldn't run the wire for nothing on all the other models...
at least i dont think they would...
and if thats the case...i do nothing but sit idly by and save...
or do you think i need to "do" something to enable the feature

The ran all the vtec wires and such in all the 92 civics, regardless of vtec, as well as in all the del sols up until the 96 model, I believe. So they might've just put it there.

I think it's in all the civics, at least 92-95. However if you look at the list of things needed before it turns on, it wouldn't be on very often. The 10A draw for example means that nothing other than the engine is on.

You could install a switch to ground out the C wire (no need to disconnect it from the ECU), then leave it in low-voltage mode most of the time. I think a few minutes per trip would be enough to top off the battery. Things use about 30% less power at 12.5v.

yeah seems reasonable...as long as memory would serve me to throw the switch...
lol

svo
vtec was pre-wired only in all the 92 civics
after that...only in cars that were equipped w/ vtec engines

That's what I just said.

what page of what repair book gives this information? I've looked at both my factory service cd-rom manual (a pain in the *** to read, i like books), and hanes manual, and haven't found anything.

In the 1994 Factory Service Manual, first edition it's the back where they take apart the alternator. Page 23-128 and 129. I got the manual from Helminc.com, though I bet your cd-rom is the same thing.

how did i miss this thread. this site is getting too busy!

i recently heard from a crx hf owner that this was a feature on his car way back in the day (it was an 85 i think). field weakening.

i still want to test my car with the alternator completely disconnected (un belted) and see if it makes a measurable mpg difference.

but i need to keep the water pump going (it's all on the same belt) and not sure what kind of smaller belt to jury rig in there, since it won't be adjustable/tightenable. the panty hose trick? bungee cord?

Just get one of those adjustable emergency belts from CT. Should work well enough for a few tests.

cool - i didn't know there was such a thing. i'll have to check that out.

(and what was that about not being helpful?)
