Yep, already did that early on.

Yesterday I went to see my mechanic and he lent me the use of his Triumph factory electrical tester, has a built-in resistor. Pretty much confirmed what I'd been seeing and to boot, the AC off the alternator has to be tested with a 1 Ohm resistor to get an accurate reading (turns out I'm getting 15VAC). I also got a Podtronics while I was there. I just finished hooking it up but can't start the bike until nap time is over or I'll never hear the end of it. If the Podtronics solved the issue then I gues we got it. If not, I just made a big boo-boo and you'll never hear from me again. I'll sign on under a different identity and start with "I just bought a bike and it won't charge the battery..."

laughing I just knew that's what you were doing!

So if you're sure of the solid connection to the Tymp, and I guess you were - then it has to be the Tymp itself. If it's not then I'll just do the same thing: sign on under a different identity!
Life couldn't be that unfair! It HAS to be the stupid Tymp!

mutter mutter mutter. mad

You ARE going to let us know the result - right?

As soon as I get definitive results, yes I'll post them. I did start, run the bike a bit with the factory tester hooked up and saw a rise to 14V across the terminals of the battery after a bit but I want to duplicate this test with the wet battery, which I know is fading quickly.
Things are lookin' up.

I just find it hard to believe something like the tympanium actually packed it in, just gave up the ghost on my way home one night. Am I the first guy in the world to have one let go?

Fantastic!

In anticipation - I'm stopping off on the way home to get some brown fizzy pop, so I can celebrate tonight! laugh

Back from Ohio...
Using the Triumph test box I got the following readings:

Readings taken across Tympanium red and black wires.

Alternator turning 3450 rpm
No load (1 ohm resistor switched out of circuit) 6.5 volts 0 amps.
Load (1 ohm resistor in circuit) 9 volts at 10 amps (meter is not true RMS meter).

Triumph test box leads wired as follows:
Black voltmeter lead from Triumph test box to Tympanium black wire.

Red Triumph test box voltmeter wire to Triumph test box black ammeter wire.

Red Triumph test box ammeter wire to Tympanium red wire.

Readings taken from batteries in different state of charge ranged from o volts to over 17 volts.

Readings taken from a KNOWN GOOD BATTERY were just over 14 volts.

My Greenlee True RMS reading voltmeter was problematic. I could not get it anywhere near the alternator, or its leads, without the RF upseting the electronics. The readings varied randomly and could not be used for testing. The meter worked if I shielded the wires/box.

Readings taken with a generic digital (none True RMS) meter gave typical readings. As with the Triumph test meters, the readings vairied depending upon the condition of the battery.

Pictured below is a Conductance testor.

There are hundreds of web sites decribing the technicalities of conductance testing a battery.

Hope all went well in Ohio.
I might have time tomorrow to repeat above tests as outlined.
I took my huge boulder out for a spin this evening after wiring up the Podtronics. Triumph test box is nice because it's ****og; the multimeter can't handle all the interference. All seems to work well but the Pod seems to run pretty warm to me. I never bothered to check the Tympanium while running because it was under the seat but I can reach down and touch the Pod unit. Seems like it's working hard to dump heat. Just my observation.

Podtronics makes a unit designed to handle 200 watts... you can also run with the head light on, as this will reduce the amount of work the Podtronics has to do. In the same vane you can use a higher watage head light bulb to soak up the extra output.

Victory is mine!!

Podtronics is working, battery taking a charge, rode home today all lights blazing and all went well. Now I have to find a place to mount it where it won't interfere with the sidecovers I just got yesterday.

Thank you, everyone.

I am now in posession of the world's only failed Tympanium unit. I'll put it with my photographs of the Yeti and that piece of UFO, and the plaster cast of Bigfoot's footprint.

Yes, unless the tympanium was just masking another intermittent problem, but I highly doubt it. I also hope so because this is costing me another 80 bucks!

Apparently the Tympanium failed first, and it was just getting by on the fail(ing) stator, which came out in more than one piece. I thought it was entirely the stator. Then when the new, 200-watt stator was put into use it could have pushed the Tymp past the threshold. I'm just guessing here, but given the symptoms and the timeline of events, its my best guess.

Sisyphus: Send me the old Tympanum and I will put it on my test bed and see what it does with a know AC power source.
If interested email me!

Sysiphus, don't feel bad about the Tympanium. I had one fail a year or two ago and tracking it down drove me crazy for several months.

What symptoms did the patient present with? I'd be curious to know. Riding along, all of a sudden no power? Batteries wouldn't take a charge?
