I would not take the chance with a $400 EHC. Find another motorcycle battery or a lower amperage jump box. Maybe a smaller lawn mower battery or something like that.

Is the battery completely dead? Have you tried to charge it? Just bought a battery charger for about $30

Yeah the portable battery pack is the way to go, not as many CCA so less chance of it F-ing up your EHC. IF you have to you have to, no other way of jumping your bike I guess you have no choice other than to jump it with your car battery. Maybe turn your lights on in the vehicle you are using to jump it, that will take and put a little draw on that big azz car battery.

Yes you can use a car battery, as long as the car is "NOT" running!
Agreed, use much caution to the connections being correct! :2thumbs:
:nono: But it won't hurt the EHC as long as the car is not running and it's not connect improperly. EHC doesn't know whether the batt. comes from car, bike or lawn mower. And the added amperage rating won't matter either way, the EHC only pulls what it requires. :2thumbs:
:2thumbs: There is a "BIG" misconception about jumping BDMs! Jumping the BDMs from any battery can only "possibly" cause the (older models) fuse to blow, (newer models) main breaker to trip, due to excessive current being drawn while cranking with the dead battery trying to "recharge" itself at the same time from the jumping battery. A larger battery or while a vehicle is running, only adds to the potential possibility of a problem. But nothing else blows up or gets damaged if connected properly, and nothing else on the bike that isn't possibly already damaged previous to jumping.
The vicious wives tales on these bikes are hell! :lol:
Hope this helps.

Insert title here...
:iagree:
Making sure the voltages are the same is the most important thing followed by making sure you connect things in the proper order!
1. First connect a red clamp to the (+) positive post on the dead battery. Then connect the other end with the red clamp to the (+) positive post on the good battery.
2. Next connect a black clamp to the (-) negative post of the good battery.
3. Now connect the remaining black clamp to a solid piece of grounded metal if possible (it's best if it is clean and non-painted). Avoid connecting this clamp to the negative post of the dead battery if you can. (There's less chance of making a spark that way!)
Bon Apetit!

Now that's putting things in "Simpleton Terms"!:iagree:

I didn't think of going that far! :loony::crazy::bang:

the fuse or breaker is inline of the VR and battery.
what protects from any 'spike' from jumped battery to electronics?

in between them :2thumbs:, yes!
I'm guessing that you are referring to the EHC electronics?
That protection is all internally built in the EHC, like in most all other electronic products. :2thumbs:
If not, that might explain a lot of the problems incurred with the EHCs! :loony:

if you have a trailer that your bike is in , and it has a roof vent.
install a solar charger on the roof!!!!
that,s what i use for my 650cc atv.

Exactly!!! Yes the EHC does have built in protection to allow small excessive load draws to trip the circuit breakers inside. However, the EHC is the weakest link and can and will burn itself out if receiving too many amps. Why do you think it would make a difference having the car on or off? I have replaced numerous EHC's and a lot of them burned out from using a car battery, even with the car not running. You are better off charging the battery overnight or going to a Harley dealer and buying a new battery. Your MAXI fuse or main circuit breaker will not protect your EHC. The EHC receives power directly from the battery. The only thing the Maxi fuse or circuit breaker is hooked into is your charging system, Voltage Regulator (hooked between Battery positive and voltage regulator) Nothing else should be hooked into this.

tech, I'm not trying to be a smart azz or argue with you, but maybe you can answer a few of my questions regarding your statements here.
"small excessive load draws" That's a contradiction in terms! So which is it small or excessive loads that trip the breakers?
Thus by jumping from a automobile that is running, do you not think that spikes from the automobiles charging system (higher amperage) trying to recharge the bikes dead battery, the slightly higher voltages induced by recharging the bikes battery "would be more prone" to possibly trip the main auto breakers of the EHC or damage other parts of the BDM charging system?
I'm just very curious as to what you're saying or trying to say.

With the automobile "running" the charging system of the automobile is operating and directly connected to the battery.

A 12 volt battery, is a 12 volt battery no matter what the CCA rating is. Are you saying that the EHC can tell what CCA the battery is, connected to it?

Thanks for the info I didn't think it would hurt anything as long as the car wasn't running, just wanted another opinion. I got the bike running, I allways keep in on the charger when at home but I had the dog at a friends house for a couple of weeks and the battery died, he did not have a charger.

Mach1,
FYI: If your battery died in 2 weeks, you need a new battery. Really weak, but still enough to start, OK. But weak enough not to start, No Way!
Get a New Battery Brother! It's on it's way "SOUTH"! :2thumbs:
