Prestolite AS123 intermittent charging fault

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?

24v Alternator overcharging

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?

Questions on Ambulance Alternator

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 :)

AC203RA Alternator Trips Switchboard Onboard Ship

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.

marine alternator

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?
