Bonneville America Forums Forums Technical Forums General Tech Charging system upgrade????

I while back I found a post about doing some mods to the charging system to get a little more out of it but I can't seem to find it I tried a search no luck there

If it's the one I read it involved increasing the wire size from the alternator to the battery (if my memory serves me well).

Nope - same but different - it was more explanatory than that one but same idea. I think it may have been by Old Roadie tho.

I have a hard copy of an article that was on www.triumphrat.net

It is titled weak charging system. you may want to try there and do a search.

That's the one. Well done Henry.

Anyone have a link only I can find is for a Daytona are the charging systems the same?

I found it it's called charging system voltage gains by Donnie_fair

On the same theme , how do we work out the drain on the charging system with lights before damage can be done
, i have a 100/80 W Headlight light bulb and was thinking of using a light bar as well , would the system in the America handle that type of load and how do you calculate it
Thanks

Ok got it done I was going to wait till this winter but I started last night and finshed it tonight I took 2 FEET of wire out from the gen to R/R got rid of one quick disconnectors cleaned the fuse box and some other connectors and went a head and relocated the batt to under the seat and the results are before change I at 1500 rpm 12.90 to 13.20 after I had a strong 14.45 to 14.70 I call that a good mod

Nice!

I was going to start a new thread on this, but this seemed relevent. I was having charging problems with my bike, I am on my third battery in 18 months since I bought my bike new. When you put a voltmeter on the bike while it was running it was showing 13.5 volts but my battery was continually going dead unless I kept it on a charger all the time. Took it to the dealer and when they tested it they found that it would test OK when they first started it up but then the voltage would drop when it got hot. A new voltage regulator was ordered under warranty and after it was installed it was charging at 14.3 volts. I think that the rewiring with a heavier guage wire sounds interesting and certainly sounds reasonable, perhaps the factorys light guage wiring helped lead to the early failure of the regulator? The only accessory that runs off the electrical system is the factory lightbar, I wouldn't think that would overtax the charging system.

There is an interesting thread on RAT about this mod and also a regulator/rectifier upgrade mod by the same RAT member.
He recommends a Yamaha R1 R/R for all bikes that use a 3-phase stator - I'm just not sure if that includes our bikes. He has done the mod to a T100 so it should be good for us too.

Looks like a new plan/mod for me.

I drove it night before last and I notice the headlight was brighter Iam going to look into a R1 R/R and I was lookin at headlights at summit they got the ones that us a H4 bulb so u can get higher wattege
