no. not quite...So let me get this right when the alternator iz properly hooked-up w. the battery cable hook-up to the alternator the van will not start. however when the battery charger is hooked up to the battery the van starts and runs fine on the battery alone.....but you say the alternator is perfectly fine from testing it for voltage....
That seems like it might be the issue... perhaps the regulator in the PCM went bad so the owner used an external regulator, which also failed. Have you tried removing the external regulator or replacing it with a known good one?as of this morning.. we have noticed that someone put on an external voltage regulator that bypasses the one in the PCM...
well you win becasue it was the regulator.That seems like it might be the issue... perhaps the regulator in the PCM went bad so the owner used an external regulator, which also failed. Have you tried removing the external regulator or replacing it with a known good one?
You said the alternator still charges, but at 11 V? I think that rules out a bad ground or connection.
Wow, that's a pain. Hmm, that thing has a worm and sector gearbox on it, right? There's only a few options that I can see:well you win becasue it was the regulator.
we are so fed up with this van... its been here almost a week.. .and its broken again
the charging system is straightened out...finally. but now there is a steering gear problem...
we replaced the gear box when we first got it along with fixing the charging.. we went to test drive it... and ... the new gear box broke!
so fed up
Or bad installation.Wow, that's a pain. Hmm, that thing has a worm and sector gearbox on it, right? There's only a few options that I can see:
1. The new gearbox you got was bad
2. One of the supporting parts is bad, causing the gearbox to break again, i. e pitman arm, idler arm.
3. Perhaps severely bad alignment? I don't think this is likely, and maybe not even possible to cause the problem, but it's a related thing I can think to check.
4. You REALLY romped on it during the test drive.
Hopefully you had a warranty on the gearbox?
Forgot about that. Always a possibility.Or bad installation.
1 .. when both tabs have voltage. this means that the fuse is not blown and there is power moving through it.New question
Knowing how to properly test fuses is a critical skill for anyone who works on their car. The best way to do this is to measure voltage individually at each of the two small metal tabs (service ports) located at the top of the installed fuse.
Answer all of the following questions to win Knowledge Test:
1) Provide a clear explanation for what it means when both tabs have battery voltage.
2) Provide a clear explanation for what it means when only one tab has battery voltage.
3) Provide at least four separate specific explanations for why neither tab would have battery voltage.
No winner will be declared until one member answers all of the questions correctly.
Good job Chris, but:2) or a short is present elsewhere in the system
3) another fuse link further down the line is blown.
4) a short in the fuse box..
there may be a short in the actuall accesory.Good job Chris, but:
(2) and (4) are potentially overlapping answers. Please distinguish.
(3) Please be more specific about the location of the short.
Also, you only mention shorts as possible causes. What else could explain the lack of voltage?
Chris wins again. Congratulations.there may be a short in the actuall accesory.
Incorrect. This would lead to condition 2 (voltage at only one fuse test tab) not condition 3 (voltage at neither test tab) in my original question. But your answers below address correct possibilities.
another thing that could be lack of voltage... a relay... or a break in the wire
Absolutely correct.
The question is about the IACV not the FITV. The FITV information was just background. Give it a shot.
Answering an age old question that was already answered.. THREAD REVIVAL.The idle control valve controls the cars idle untill the thermostat opens up to allow the hotter coolant to flow.
When the hotter coolant finally reaches the IAVC, the idle returns to normal because it has reached normal operating tempurature. final answer
By the way, anyone interested in learning more about the IACV and how it works should read this thread.wait a min........... I knew this and read the question wrong lol
I fail
