I will upload a photo of the back of my TB1, it's known good operational. I pulled all the 12 lead wires off so I could pull the bell apart and do testing, but I left all the small ring terminals in place where they go. You wiring, other than missing some wrap that likely degraded and fell off...

Hey all, Looking for a rotor for a 60hz MEP006A 60kw gen. Mine is electrically faulting to ground. Please send any leads my way. Thank you!

You'll want to look and see if the motors are delta or wye. It should be on the data plate.

Yay for progress. That voltage select 'card' is set for 120/208 WYE currently. If you move it up one, you'll get 240/416 WYE (not delta). The way it is currently, at 1800RPM/60hz you should be getting 120V between T1 and neutral with everything set correctly. You can check output HZ with the...

You mentioned that you measured 3ohms across 15 + 16 headed to the alternator? If so, you should be drawing some current when you apply the lab power supply. Perhaps you have a bad lead or the meter fuse it blown? Can you post a photo of your setup?

Well >10 years later, finally circling back to this generator as I have some renewed use for it. I left it with 6 new rectifiers installed but clear evidence of burnt wires on the exciter rotor. I pulled the end bell off last week and started repairs. Found that just the 3 cables running...

This should be the field current specs. if I'm reading the manual correctly.

There's a lot of skilled folks here so I'm sure we'll figure it out. I'm fighting an issue on my MEP006 where my field current is higher than it should be. I'll be posting that separately but happy to help here as much as I can.

Do you have your test rig wired up like this? 15 and 16 being the F2 and F1 terminals going into the main alternator. Have you confirmed the fuse is good in the meter? Also hey from just up the road from you. I was down in Lebanon last week working.

I would like to 2nd the idea of starting on diesel, then switch over to your alternative fuel once it is warmed up. In the Mercedes turbo-diesel world, I always shot for fuel temps of at least 150F when running WVO. I attained this by running a hose-in-house fuel line from the trunk (where the...

Looking at that schematic, you might be able to tie the two similar functions together with diodes (if it can deal with the V-drop). that way you could use a DPDT Just a thought!

Duh...sorry I wasn't thinking :-) Does this one look correct? 6GG5B-73 Carling Technologies Toggle Switches Momentary, on, off. Not sure if double pole or not...would want to check inside genny to see what it is.

I might have to ride my motorcycle down there and have a look-see. My MEP-006A is in Newberg, as well as my 404.1 German NATO Radiobox Unimog Both a little blocked in at the moment :-)

Switch shouldn't be anything amazing. You need a on-off-on switch with momentary one direction, and not in the other. Probably DPDT (double pole, double throw). If you happen to come across a generator for parts, I need an exciter winding in-case the repair of mine does not end successfully...

Yes.

BTW nopics :)

Delta/Wye Explanation: http://www.teal.com/newsletter/AppsNote15.pdf You'd want to be careful about your loads and how they are configured relative to the generator. Transformers included as well. The 4 output connections are on the left side (as viewing from the control panel end). The door...

PM me if you have any issues. I'm pretty familiar with my MEP006. Later!

Have you confirmed the voltage card is in the right position? One sets the generator for 120/240V and the other for higher voltage. My MEP006 would output 477 phase-to-phase but anything higher would kick off the over-volt limit and shutdown the gen-set. I would connect a multi-meter across...

Sorry should'a mentioned dealing with bigger than the average generator :-) I have a meter already that I might throw in just for checking each phase for good match at heavy load.
