ECH fire.

Hi all!

I have a -05 Pitbull.
yesterday when I was riding my starter engaged, all instruments went dead and I could not turn the bike of with the ignition.
the starter kept going until I managed to disconnect the battery, which probably means I have a fried starter motor and perhaps some junk in the trans by now.
It turned out I had a fire in the ECH. The box is a ECH 58c from Elektronikbox.
The question is, do you think it’s only a faulty box or could it be stator/voltage regulator fault?
I’m a Harley mechanic but this is my first BDM electrical system.

Its a strong possibility that ur stator/VR took out the ehc. Unless you changed it out per ehc instructions I dont think there will be a warrenty? Holler @ Curtis @ WSW. Pick his brain an order a new one. Electronik Box in 04 Pit still going strong...knock on wood.

I’m not sure what’s been done to it to be honest, I’ve only had the bike for a month. How can I see if the stator/vr is changed?

Welcome from NJ,
The battery itself may have shorted out. There is a circuit breaker between the VR and the battery which is to protect the battery if there is a fault in the VR or wiring. The Ehc should have an additional CB installed to protect it from a shorted battery. Depending on who installed the EHC 58c it may not have been done . For the best info you may be able to direct message AXEL he is one of our members and also makes the EHC. This link is a file for your Charging System which may help you.

So your stater kicked in while the bike was already running?
Since you couldn't stop the starter, I'd check the handlebar switches for a short.
The starter is not designed to run more than say 5 secs at a time on most bikes. After that everything heats up way to much from the very high current draw and then contacts can fuse etc and you are sol.
Good luck with this, but remember to check everything from switch to VR, starter and EHC
Did you see the fire in the EHC, is it visibly burnt?
When I had a similar instance with the stock EHC, the starter and battery took the hit but not the EHC
The massive power does not pass thru the EHC on the way to the starter.

Yes it went on while I was riding. I couldn’t turn the bike of at all with the ignition. I will of course check the button for shorts, but as the current shouldn’t go through the ECH I don’t know why that would cause this problem. The ECH was literally on fire and it burned a hole in the middle of the box. I will put a new stator and vr, new box and battery on. I guess the starter is fried as well but I haven’t had time to find out yet. Hopefully the rest of the electrical system is ok as I have checked for burns in the ECH connections and found them ok.

If this ever happen to you again, as far as the starter staying engaged, just jerk the green wire off the starter and it will stop it from continuing to spin
Well if it happens while riding as described I doubt you can stop safely and get off the bike fast enough for it to matter. I know I couldn't at my age.

You don't happen to have one of the Spyke slam buttons that has a nut on the inside of the cover, do you?

That thing is the worst, if that nut comes loose on the inside they use to adjust the throw it can engage the starter while riding and doesn't matter if you pull the solenoid wire it will still keep going...

ALWAYS carry a 10 mm wrench.
Yeah I do. But the battery was pretty much dead before I got that far. I was doing around 70 on a pretty big road, so it took a while to stop, force the engine to die and get the under the seat.

Mine did pretty much the same thing on my 04. I had a wire break off the battery and when I put a new one on the starter just kept turning over. Turn key off starter stopped. Turn key on starter engaged. Faulty EHC. 2 year warranty. If you put a new voltage regulator on with the EHC swap.

Hi Henke,

I just have seen the thread and I think, everything is told already. Pls. check the input buttons and the charge regulator. A death battery also can result that the charge voltage increase over 18 Volt, resulting that the EHC output might burn if higher voltages are present.

However, I would suggest that you send the EHC to me for a check and I´ll take care of a change in case of an issue. Pls add the rma formular to the package what you find at: https://www.elektronikbox.de/shop/index.php?main_page=page_3

All the best!
Axel
