08 mastiff randomly shuts off

[loudmastiff]

So I havnt road my bike much in last few years.. Noticed it last year a couple times and then the other day.. Will be going along and engine will just shut off . Sometimes it will fire up immediately other times I had to wait a a minute or more.. It's pretty random I'm sure this is gonna be pointed toward ehc . But anything else cause this.. It always has started back up.. Give me some ideas to check

Gas cap? vapor locking, loosen the cap next time and listen for the rush of air

ehc means watt? It means 12v goes into 5v working a 0.1v to less than 4v = 12.8v is a well charged battery sitting static... been sitting how long not being trickle charged all this time?

That or... Alex, for $200, I'll take... ehc takes a shit when the horn blows.

Battery is brand new.. Deka brand 310 cca.. Turns over just fine.. Horn has never went sounded.. But then again idk if my horn works.. It's sounded like shit from day one.. Bike only has 5500 miles..

Same happened to me guarantee it's the ehc no question

Should do an inspection of wiring harness, could just be chaffed wire, loose connection, etc. If this is the case, Axle's unit wouldn't solve the issue.

Don't waste your time fuk'n around, if you buy D O C s you get a new harness with it and you don't need to screw around trying to find a short in yours if that is the problem, finding a short or loose connection is not the easiest thing to do, by the time you do all that you could have the new harness and ESC installed, spend a little time doing it right and NEVER worry about it again.

Very well said, I think I've heard it before and still rings true!!

Random computer bike speak:
ROM = Read Only Memory... as if a new laptop/PC was taken out of the box, plugged in and turned on ready to go.
RAM = Random Access Memory... as if the lapper/PC is slowing down from new, with all the porn downloads, ass crack and vaginal gash photos.
Format = Wipe all the RAM away so ROM is all fresh again like new.

Translation:
1. I pull the hot and ground connectors off the ehc.
2. I ground both hot and ground wires to the ehc/frame of bike; to empty the (memory) millivolts in the capacitors.
3. I solder a Y-connector so both the frame ground and battery ground are hooked up to the ehc.
4. I have a bulletproof ground because the ehc is directly attached to the battery too, so no questioning the ground.
5. I tighten both ground and hot cables so the ehc does not lose power and begins at 0000 again.

Get it?
