General ALternator question

[shinnlinger]

Hi,

The problem is the machine wont start after a while due to dead batteries, but it is manageable if I put it on a charger once in a while, but I figured I should look into fixing it up.

Was working on the roof yesterday (I am using the Lull to do this) but poked around the alternator beforehand. The middle bolt has the same 12.3 volts the battery does all the time, so I assume this is the feed to charge the batteries if the alternator was working. The two loose wires that hang around the alternator don't have any power, key on or not, but there is no obvious place for them to connect to the alt.

Turning the key on does get the electric fuel pump clicking, and the oil temp gauge will move, but it wont start the machine due to a bad solenoid so I have been starting with a crowbar(working on that too, any one know where I can get a UNI POINT solenoid, UNI9-11???)

THere ARE some lights on the dash, but they don't work. The dash had been painted and the stickers removed, so I don't know what these lights refer to, but it is logical that one is the charging light as has been previously stated.

So now what? SHould I jump another wire some where on the alt to try to energize the field? SHould I look at testing the regulator? THis is one of those things that is a minor inconvenience so I don't want to spend much time and money on. I have some other alternators laying around, but I want to rule out that it is the alternator first vs some wiring issue.

G'day can you get a better close up pic of the back of the alt along with any markings on it and post?

I had the same problem as you, I had to charge the battery every time it dropped below 12 volts, this none charging issue was my own fault due to me disconnecting the idiot lamp to install an amp meter, sounds to me that maybe someone has disconnected the idiot lamp on your machine, I never thought that doing that would creat such a problem, but thanks to the guys on here I finally got it resolved, I had to explain every little detail that I had done though, but I would start at looking at the wiring diagram if you have one ,mine was under the hood of my compact tractor, but perhaps you won't be as lucky, I do have great faith in the members on this here fantastic forum, and I know for sure you'll get your machine up and runnin' I really don't get the idea of you having to short out the solenoid usin' a crowbar, I had the same problem with my little rider, but used a screwdriver, I have since fixed that problem,bein' the main hot wire was not connected to the key switch due to water getting in the key switch, you may have the same problem, it may even be a bad ground, like the ground(black wire) may be broken between the ignition switch and solenoid, an easy fix, good luck to you on correcting your problems, take care...........AMPA
