booster pack/power pack as power supply ?

Just got back to working on my bike after a break spent focusing on my studies.

I have a couple of electrical problems (charging issue) to deal with. These power/booster packs are on sale right now, and I was wondering if I could use them as a power supply connected directly to the + and - leads on the harness, instead of killing my battery.

PowerBox
Booster Pack

Sorry if this has been asked before, I couldn't find any relevant topics with various keyword combinations.

Thanks!

As long as its 12 volt I dont see a problem with you using these booster packs. Plenty of juice in these packs.

So you're going to be running a total loss battery system? No way to recharge it while riding? It should work as long as the current drain(amps) does not exceed the power packs storage ability & it's recharged when not needed.

So the power is going to continuously drop away till it jsut dies and cant re-start??? Thats hard on the electrics - I wouldnt recommend it.

Good luck - maybe fix the charging system.

Thanks for the replies !

Sorry, I didn't explain myself properly. I meant that I wanted to use the power pack instead of the battery to test the various components of the charging system while working on the bike in my garage, and not for riding with the power pack.

I had the R/R tested, and apparently its fine. The resistances from the stator wires were all around 1.5 (which is above recommended resistance specified in Clymer manual), And I'm getting 18 V - AC on idle. I forgot to test it at around 4000 rpm... Shall do that, and hopefully come back with some good news. . .

Yes, a 12-14 volt D.C. power supply connected to the battery cables(observe polarity, please) will work to check out the systems. I use a 12 volt D.C. 15 amp one when testing out new light circuits.

Updates:

Alternator assy is fine as well, getting 50V A.C. at around 4000 rpm. Oh electrical problems.
The 6 pin connector looked like the plastic melted a bit as well, maybe new connectors are required.
I'll find the problem eventually. . .

Quick question though : if I'm getting proper A.C. voltage from the stator (approx. 50V), but recording higher resistances (around 1.5 Ohms) than stated in the manual, does that mean stator is defective ? The important part would be the A.C. voltage, non ?

Thanks again for the help !

The important part is AC current and voltage. Both are required to deliver power. If there is a high internal resistance, a voltage test, alone, might not show it. That's why a voltage test can be used to identify a bad stator, but it cannot confirm a good stator. A true test is to test it under load, and isolate it from the rest of the bike, but that is not easy, (not impossible, but not easy).

If the resistance on the stator is higher than it should be, then that does make it suspect. But make sure the meter is good, or try another meter to confirm.
