Please Help

Hello, I am in need of some ideas on what could have happend. The wife and I took a ride for alittle over 100 miles, 89 Heritage running great, cranking good, started to head back I hit the starter, just clicked, checked lights just fine. Got some other bikers to push me off and it fired right up, I went about 10 miles and had to get gas, left it running, Put it in neutral, light was very bright, went 2 more miles I no longer had any lights all were blown. Stopped at a gas station and it idled for just a minute then it just shut down, I could just barely could see the neutral light. My HD battery is just 3 months old. So what I have now is one very fried ECM, a battery that is completely dead,(won't charge at all on battery charger) and every light on the bike is history. So does anyone have any idea WTH could've happend? I'm sure with all of the knowledge of the members on this board, someone can help me Please. Thanks

Also, does anyone on here know here to find an 32405-91 ECM, I've looked on ebay, not much to offer. Thanks

Sounds like your regulator quit regulating and you were overcharging, you'll probably want to run some tests on your stator too...Factory Service Manual and a VOM multimeter is all you'll need to test....

Stock ignition module for your '89 Heritage is 32405-88A...the number you posted came out in '91....I'd suggest a Dyna 2000 module which would go in the stock location or a Dyna 2000i nose cone...Ultima has nose cone ignitions that are the 2000i with their label and are a little cheaper...sig pic below is a '90 Heritage and I'm running a 2000i nose cone ignition

Thanks for all the ideas. I have been doing tests according to the Service Manual, so far my stator checks out as good, with the fried ECM hooked up, I have power to the coil. My question is, my battery is flat out dead, (just 2 months old) and won't take a charge at all, from battery charger. Could this battery going bad cause all of this? As per SM there's no way to check the voltage regulator, so that will be another item to purchase just in case. And I've decided to go with the Dynatek 2000i Ignition (Thanks Lucifer) And will this Dynatek ignition do away with the ECM under the seat?

Looks like it replaces the ECM module. Here is a link: http://www.powercommander.com/downloads/Support-Released/Dynatek/Manuals/D2Ki.pdf

As to the battery/regulator issue, either can cause failure of the other if it fails just the wrong way.

Yeah, it replaces the stock ignition module...The 2000i goes in the nose cone under the points cover it also replaces the ignition pick up sensor

Or you can go with this module...it mounts in the same place as your stock module and plugs in to the pick up sensor...

When the regulator went south on my Heritage, I looked at the jell on the back of it and I could see it bubbled above the part of the circuit board that burned out....not a foolproof way to check,but if you see the jell pack lifted off the circuit board,you know it shorted....
