Title: Battery Eliminator
Post by: Diablo007 on August 14, 2020, 02:32:10 AM
So, a motorcycle charging system puts out, for the sake of argument, between 13.5 and 14.5 volts.  I know this isn't 100% accurate, but it is less than 16 volts.

Can I use a 16V capacitor as a battery eliminator?  The ones that I've seen advertised are usually 35 volt.  The reason that I ask is that I am an IT tech by trade.  I've found 16 volt capacitors in more than 4700uF in working computer power supplies, but the computers are being replaced as they are out of date.

I'd like to use one or more of them as battery eliminators. Will this work?

Capacitors only work on bikes with permanent magnet alternator. So that rules out all US market aircooled RDs with stock charging setup, and any other bikes with carbon brushes

why run it at o that close to the limit? fit a higher voltage and at 35,000 uF is always good for a cdi.  :twocents: they are cheap new.

Do they get wired in series or parallel?....

wire it like a battery.  terminal near printed side strip is negative.

OR, just get one from John at economy, its packaged well.

A lot of people are going to VAPE or HPI ignition to eliminate the battery. I've been stranded too many times because my battery wasn't charged or charging.
