Where is the voltage regulator on an older 1986 Honda Prelude?
is inside the alternater
The voltage regulator has the job of making the voltage 'constant'. In most modern vehicles the regulator is located in the alternator, in older models the regulator is located separate. If your voltage is jumping around a lot then you either have a problem with the battery (batteries stabilize the voltage also)or the charging system (and probably the voltage regulator)
A 1970 ford has a external regulator It's probably possible to adjust one by ajusting the contact points inside the regulator and I'm assuming it has a older style regulator but I don't think it will do much good. Replace the regulator. Disconnect the battery hook up the regulator hook battery up and boom it's polarized.
Voltage regulators are often built into the alternators now, this wasn't always the case. Older vehicles had separate voltage regulators mounted on firewalls or the side of the engine compartment, wired in between from the alternator to the battery. The positive lead now goes directly to the battery from the alternator/regulator.
If your voltage is normal at idle and shoots up as you increase RPM, then I'd say your voltage regulator is bad. In older cars, it is a separate part, but most cars, it is built in to the alternator. It is more cost effective to replace the whole unit. You can have it pulled off and tested at your local auto parts store.
If not the alt or battery what could cause a 1979 Chevy Nova with a 6 cylinder in-line engine to stall and die at decreasing amounts of speed?

Ah, you have made one of the most common and easiest mistakes to make in automotive maintenance. Because the 'battery voltage' idiot light came on, you assumed that the battery was bad. Did you have an automotive electrical specialist test the electrical system on your car? Did you have the battery tested at a battery shop? Did you know that there are 3 primary parts to an automotive electrical system, and anyone of them can…
it converts AC line voltage to DC low voltage. at first by transformer it setps-down the voltage then it rectified by bridge rectifier ckt. by this there is rippled DC output is there. then is this fed to filter circuit to filter the ripples and its given to regulator circuit to produce fine and smooth pure DC voltage. nowady SMPS (switch mode power supply) is use rather then older iron core transformers. SMPS have plenty…
Considering there were five generations of the Honda Prelude, this question needs to be more specific. The Prelude lineup featured a variety of engines over the years of different engine families, ranging from 1.8L to 2.3L The fifth generation Prelude (1997-2001) featured a 2.2L DOHC VTEC engine rated for appr. 195-200bhp. The fourth generation Prelude (1992-1996) featured two different engine families, the "H" engine and the "F" engine. The "H" engine in the 4th gen…
Bad voltage regulator. Replace it. Should be built in the altenator. Or just replace the altenator. Make sure you're battery is disconnected first. Also connect battery back up after you mount new altenator. Note not knowing year of van some older cars have a external voltage regulater. Which means it will be mounted someware on the firewall or inner fenderwall not in the altenator. Make sure you disconnect battery before working on any electrical. This…
A vacuum tube is a current amplifier where the transistor amplifies voltage A tube is a voltage amplifier. A transistor is a current amplifier. A tube is an older design that requires substantial voltage to operate correctly. A transistor is a semiconductor device that operates on relatively low voltage.
F100 runs but when shut off it will not start again. Alternator light works when I try to start again. If I jump battery truck will run fine until I turn it off and try to start again.?
Try having the alternator checked at a local parts house, off the truck and on. If it tests good on a bench tester, then bad on truck, then you might have a bad voltage regulator or wiring problem. If it's an older ford, (should be if it's a 100), then the regulator should be separate from the alternator.
My 97 vtec Honda prelude stalls out while I drive I had diagnostic done with oil change trans flush cooling flush I didnt have cash 4 radiator upp lower hoses PS flush etc. What is the malfunction?
It depends on the year of the vehicle. Newer (late 60s/early 70s on) had "internal regulator alternators", so the alternator needs to be replaced. Older cars have a regulator, usually mounted on a fender well, the fire wall, or the radiator support which canb be replaced independently of the alternator.
Currently, there are nineteen car models for selection at honda.com. However, if you are looking to buy a Honda car of your own, you should look for a Honda dealer near you, since the car dealer may not offer all of the models listed on the Honda website. A second-hand car dealer may also have older, retired Honda models that are no longer on the Honda website.
Internal or external regulator doesn't matter. you can see if it's putting out by running a voltmeter across batt terminals with car running also if it runs with batt disconnected or generates a magnetic feild, it's working. . If it's an older external, you can even change to internally regulated type with the right adapter. if you need to know stock output, need vehicle info.
