I believe I have a Leece*Neville, Model 8LHA2023Y as it was scribed by hand into the alt. body by the previous owner.
The alternator was removed from the 1977 Perkins 4108 marine diesel eng and sent out to be refurbished over a year ago. I need now to install it back onto the Perkins. I need to know the wiring diagram. Unlike some of the later 8LH series, mine is more similar to the current 8LHP2170V.
looking at the back of my alt, there are 3 terminal posts on top, the NEG OUT on left, POS OUT on right and a single terminal post at the bottom.
I am aware that one wire will connect for the tachometer and the other to the ignition switch, and of course Neg to the block and Pos to the battery, assuming this is correct. I need to know which terminal post is for tach and which is for ign.
Can you help me?
I believe I have 4000 series, there are no markings (tags) on the altenator but it looks like the 4000 series. It is on my RV and older crown school bus I am sure it was an aftermarket.
It does not seem to charge at low rpms, it does put out some voltage at idle but very low (everything dim). I will check the idle output voltage today. The dash volt meter reads 11V when running and battery disconnected.
First I would like to verify the existing wiring. The + - are obvious. The (ign?) terminal has a wire running back into the body of the altenator. I am only guessing this is the (ign) terminal from the position on the regulator - there are no markings. I want to know if this is correct wiring or something special? Except for the +- connections there are no other wires attached.
Altimately my goal is to have a system at least charging at idle
I need a alternator that can generate 120V, 15A and up. I know it's not market available. What I really need, is a alternator with a multi(12 or 18) pole pair stater (not the rotor magnet poles). Then, I will connect the multi coil of each phase in series. In this way, the voltage rating can built-up while the current rating degraded with a factor of pole pair number in each phase.
anyone has any idea that the part number of a multi coil stater (normally 12 coils for a 4 cyl car and 18 coils for a 6 cyl one)? the power range is about 2kW.
Thanks a lot.
I have a Prestolite AS123 alternator in an inland waterways marine application. The charging system has developed an intermittent fault whereby the ignition charge warning lamp occasionally comes on and the alternator output drops to zero. I have replaced the alternator regulator and checked all the wiring, but with no fault found to-date. Can you please tell me if this fault could be caused by an intermittent short circuit to ground on the wire between the IND (D+) terminal and the ignition charge warning lamp? Also, can you please provide a wiring diagram for the internal wiring of this alternator?
Recently I fitted a rebuilt 24vAlt to a loader but was called back to the machine less than a week later because it was overcharging, up to 33V.
Have disassembled unit roulette spielen and tested Reg on a Transpo tester which indicates Reg is o.k.
Rectifier appears okay, it was new and the stator was also new.
I am unsure though about a capacitor that upon closer inspection appears slightly dented/squashed. What is it's function? It has a rating of 250V and casino spielen also has 474K written on it. I guess you're aware of where it is attached to Rect.
Could it be the source of the overcharging fault?
I Need to know about the 52volt alternator output information.If i spin the alternator with a gasoline engine
at above 1500RPM. what will be its output voltage and current
at its output terminal without connecting any rectifier or inverter.
I currently own a 1989 Collins Ambulance with a 7.3 L diesel and a LN alternator which is starting to act strangely. After starting it seems to not charge until I rev up the engine. When driving it seems to cycle between charging and not charging with the amp gauge going up then back to neutral - is there a wiring diagram, something I should look for and or - is a rebuild kit available ?
Thanks for any suggestions :)
have installed new 2824LC will not charge taco wont work. if alt&ing bridged will charge but still no taco.this alt replaced a 2800JB with duvac
We are writing to you from Singapore.
We bought 10 units of AC203RA alternators from your distributor, Chop Hock Hong and supplied them to a local shipyard.
When the shipyard was fitting the alternators to the switchboard, it keeps tripping the switchboard.
We suspect the cause of the insulation fault onboard the vessel is due to the negative terminal of the alternator being internally grounded.
Please advise the solution to this problem. Your prompt reply is greatly appreciated.
I have a 1973 Chrysler Marine with Prestolite alternator and voltage regulator. The system suddenly stopped charging. I had the alternator tested at 2 shops and it was fine. I replaced the voltage regulator (#35 602) and the system is still not charging. Any suggestions as to what I should check next?
