Yep. I just emailed them back and asked if they could build one that would more realistacally reflect the starting procedures of our big motors.
If they do this then maybe we can all get a new one that won't be beeping on us everytime we shutdown the motor. Keeping my fingers crossed for a new model just for us!!!!

Ray,
The graph explains a lot, thanks for the posting. Does anybody have volt meter with a peak hold feature? Would be interesting to see what the battery voltage drops down to when starting, especially when hot. Using a digital volt meter with a peak hold feature you can connect it to the battery in reverse thus showing something like -12.8 volts. When starting, the voltage will go more positive (toward 0) and be captured by the peak hold. I've got one of these meters at home but it doesn't do me any good where I'm at now. Ray, if you would like to use my meter I'll arrange for you to get it.

When I cranked the bike this morning after it was on a battery tender all night, the voltage dropped to 8.4 vdc through the starting process. This was a cold start. The next time I checked it the low peak was 7.8 vdc and a 7.3 vdc again. Off the tender after the first crank it has about 13.02 volts showing on the battery, with the key on it drops to about 12.90 and when I hit the run and the fuel pump kicks in it is about 12.50 vdc. When the bike is idling it is seeing 13.70 vdc.
I will check it later when I come in from riding some. Neil

Ray,
I suspect that people who have increased there cranking pressure by milling the heads, zero decking etc. will use more current to turn the motor over so they should see even lower starting voltages. That would likely be interpeted by the battery bug as less life available. I'll be home around the 11th when we can test both of our bikes and compare notes. Yours being stock compression and mine is a little higher (zero deck).

Mine is good. I can see the voltage in my battery 12.9 and when it starts it shoots up to 14+. Only thing that is not inline with our bikes is the battery life. I just wasn't made to reflect the deep starting cycles our bikes put on our batteries but that is only a small part of what this bug does so I can live with it.
I just want to know the voltages. I did email the company and ask them if they can build one that will better reflect (the battery life) the starting cycle our bike endure. But haven't gotten a response yet.

Any updates? I got 13.1v on tender 14+v while bike running and 39% battery life at start-up it was at 41% earlier. Still, I'm satisfied with the voltage output reading
let's you know the charging systems still working..

I just removed mine and laid it on the shelf. I will probably give it to one of my Harley friends who is having electrical issues and perhaps they can use it to help track down a voltage/wiring issue. It just bothers me seeing low readings with a new battery even though I understand my takes a good ump to fire but even with electronic compression releases it wants to tell me my new battery is crap. I can or rather just live without seeing that everyday when I take mine off the battery tender to ride it.

I went to their website and it says the motorcycle ones are only for bikes up to 1500cc.They had one for cars that would more represent our engines.Was wondering if this would be more appropriate for our dawgs or if motorcycles and cars are too different? Any ideas on this?

Cut the ends off of mine, soldered some alligator style clips onto it and guess what? Now its my compact digital voltmeter that I keep in my travel toolbox that I take with me when I trailer the bikes to rallies

The tech Ray talked to mentioned increasing the wire guage to a bigger wire to the starter and it got me thinking.... this seems to me to be a good idea.It would in theory make our starts less demanding on the battery thus increasing battery life. Does anyone know of a reason it would be detrimental to do this or does my theory thinkin not inline with practicality.
