Battery and regulator

Can a Cycle Electric DVG-5000L (low voltage regulator) work with a 7A battery? Wouldn't charge as fast as the DVG-5000 (w/higher voltage regulator), but it would it work okay?
Running a headlight with 70/55 H4 bulb, LED tail light, and coil to fire the Power Arc dual fire/single plug ignition.
When it comes to electrical stuff my eyes get crossed, but it seems like a 7A battery is better than a 5.5A battery.

I would think you should be ok , you should still get a good charge with the reg. you have . You need to add up all your wattage use of what you are running and see if your batt. and charging system can cope with it and still keep a good charge on the batt. . I'm using a 10A AGM batt. ,CE Gen .& std charging CE reg. and I still use a battery tender just to keep the batt. to specs. system works real good.

I hope someone can help me. The battery died in my 1950 pan (converted to 12 volt). I replaced it with a 12 volt, 5.5 amp battery. Then I discovered that it was not charging so I replaced the generator and regulator (custom chrome). When I test the battery at 1500 rpm there is appx 15 volts. I rode the bike for appx 30 minutes and the lights drew all the power. I checked the regulator and discovered that the (hot) wire from the regulator to the ignition switch had disconnected from the regulator at the point of solder. I soldered it back then it happened again! (yes I can solder. I gave it a good tug test).
What is the deal? I'm going broke replacing stuff!
All help is greatly appreciated!!!

15 V is a bit high, should be about 13.2- 13.7
I bet the reg is bad. the gen is most likely okay as it puts out 15V
with that much Voltage I bet the connection is getting real hot, leading to your solder joint to come undone.
a CE reg is about the best thing you can get, or a Franks reg if you can find one.
You WILL fry that tiny batt if you run it for long.


I also think the HOT lead goes back to the term. strip under the coil. then power branches off to the switch and various other places.
what gauge wire ? should be at least 12GA MIN

At that charging rate you may also boil the acid out of your battery...MW

The acid will def. boil out of the batt. with that small batt! use atleast a 10amp AGM & youll be good. 8)
