Dyna lll install?

I have an older version Dyna lll, black box type. When I go to static time it, the light is dim all the time. I have 12v in to the box, 7.1v out to pickups. Ground is to the engine. Module must be toast??? The wires are in a loom, so I will pull them and see if there's a break in one of the wires. Just checking if anyone else has had this with a simple fix. TIA, Eric

sheesh what is it lately with dyna products in yrs there were not much failures ...and its seems recently failures everywhere with them

yep I didn't see the word old ...that's like my dynas there old too ...so you gambled and lost I guess eric ...me too ...I havnt won any gambles on old dynas either

How about testing it, anyone have any info to help Eric?

Dyna will happily test any of their units and repair as needed at an acceptable price.

Dyna wants to test them. This is a freeby that someone gave me. They didn't say it worked and at the time, I was just after the magnet piece on the cam. I fried my other one yesterday after putting on a new rear fender I must have pulled my sense wire from the reg/rec. fried my $135 battery, the Dyna, probably the reg/rec too. I made it about 4 miles and it died in the absolutely most dangerous part of the city. I had a friend who came and picked Schitzoid (my bike) and me up. I am ready to raid my running 77 for parts because this 1200 has to be ridden. I am stuck though because I only left myself room for this little Ballistic battery. Overcharge them even a little, and they are toast. I am not patient enough to send them in to Dyna. Live and learn or live and repeat,,, hmmmm.

I don't think I can check the reg/rec until I have it running with a good battery.

You might call Dyna. One of their reps might be able to walk you through testing?

sheesh eric ...this sounds like hooch ...I went from running super great to falling all over myself with stupid things like this trouble your having beef up we will both get it done

I went and messed a bit more. I am getting 2.44 v back from the coils. I disconnect the power source to the Dyna black box module and still have dim light and 2.44 v. I disconnect the pick up wires and still get 2.44 v on the yellow from the coils. The only way it stops is if I pull the relay or hit kill switch. Can a relay go bad? I have an extra, I'll try it. Sorry thinking out loud through my fingers.

Have you had a look in the Gallery?

We have a bunch of Dyna manuals. I think there are some testing manuals there too.

No, I haven't, Dan, but I will. Dyna took the testing procedures off their website. In the meantime, I went out and put the old one back in to test, the one I saw plumes, I mean plumes of smoke coming from. Was just going to see if it would make a full light, to my surprise it did. The other issue I am having is if the bike dies, when turn the ignition off, the bike throws a spark and there must be enough fuel in there for it to fire. It may actually be a slight back fire. I am running to get a fuel line clamp and will see if I can catch it on video to post. I have a car battery with jumpers for now. I'm also picking up some new fuses and plan on going through my wiring to see what else I blew up.

Well good to know what can happen if that black sense wire isn't connected.
Sorry you were the tester though.

It runs on 3-4. I'll go test the coil for 1-2 but I am willing to bet it's the module toasted on the Dyna. I'll wade brought the coil test procedure. They were both equally warm to touch after a few minutes of running. Sometimes when I shut it off it fires a big shot of flame out the pipes. I was able to watch the cam pulley and the other times it does kick it backwards just a bit. It has been doing this off and on for a few years but not very often.

On the positive side, I ran it enough to feel my reg/rec is still good. Maybe I'll just thro the points back in. I'll have to see if I have enough ballast for the 3 ohm coils. I think I have a 2.2 still.

Points have made for pretty reliable ignition and can be serviced roadside.
