Alternator ID

[LowTech]

After getting the rig starting and running pretty nice today after starting I wasn't getting any output from the alt (measured at the battery terminals).
Testing goes in several different directions based on the type, so what is this one? I believe it's a high output one that's also used in the ambo.

Looks like the ambulance style alternator to me. 190? Amps. Not too sure but thought that was the output

In my manual it says that there are these 4 types,
1. Rear terminal, external fan w/ external regulator
2. Side terminal, external fan, w/ internal regulator
3. Leece-Neville 165 amp
4. Internal fan alt w/ integral rear mounted regulator

Is it possible to tell which one the ambo version is from the front view? Getting a view of the back takes more work, especially in this rig, removing stuff. Or maybe if I get underneath I can see the back but I'm not hopeful of that looking at it's placement.

Odds are it's likely the Leece-Neville 165 amp unit as that is what was typically used on the ambulance packages, and that's exactly what it looks like from the handful I have seen. That's a fair guess and a good place to start.

You can always take a look here and see if you can match it up.

It does match up to the L-N alt even though the numbers I found on it don't exactly match. After starting this morning I added more load to it (headlights) and it activated. It read,
13.3 at idle w/ headlights on
13.6 w/ headlights off
13.7 after picking up the rpms but read at idle w/ headlights off

Yesterday when I started it to make sure it still started easy and ran smooth from the last bit of work I'm guessing it just didn't have enough load to activate it. Usually it would kick in from just picking up the rpms for a moment. Yesterday that didn't happen either of the two starts I did, one after the other. I do have a solar trickle charger on the starting batts so maybe the batts dropping to 12.6 after starting wasn't enough to activate it even w/ the rpms being higher for a moment?
