Do you mean the 3 phase regulator of last Duck?mrinflux wrote:i'm not suggesting it doesn't pay to buy a good battery. but if u don't have a trickle charger, ur wasting money. a good battery will last longer than a mediocre one, but w/o a trickle charge, even the best battery won't last very long in a 907.
peace
No need to go "to street" with multimeter(i do so, cause i want to see, what is happening, when bike is running longer time, when battery SHOULD be charged AFTER STARTING, what takes plenty of juice from battery), but seems, that You have too high Voltage in battery poles in higher rpms. I think, that 15V is already too much to normal battery, It causes lost of water already in those voltages.... My Electrex in my 907 have NEVER give such high voltage, but surely its better stabilized unit, than normal original Ducati regulator... That Your IDLE voltage seems to be ok, but 15 V is too much, if we are thinking LIFETIME of battery and i am NOT wondering anymore, that You are loosing batteries...persempre907 wrote:Antti is awesome, not me.
The top voltage I found was about 15V and at idle was about 12,5 - 13V.
In the Electrex manual I read the top voltage was about 15,4V.
So, I thought all was OK.
Also, have I to check it when the bike is running?
That voltage can be quite high just after starting, cause battery is little empty just after starting and regulator try to put plenty of current to battery. Regulator is thatkind equipment, that it runs all that current (from stator) to GROUND, what doesnt need for battery charging, so more U use lights, etc in Your bike, that helps regulator "feed to ground"/heating regulator/regulator life, etc...), BUT 907 have so "small stator", that If put some 55W dual hedlight WITHOUT switch(!!!!), it cant give anymore ENOUGH current to battery => "eating" current then from battery and sooner or later injection dont work anymore, like should.... I know this very well, cause that have happened to me with doubble lights.... Early ST2 (97,98) had plenty of these problems caused bad regulators and MOSTLY bad cooling around regulator and also one "special" (shit) connection cable between stator and regulator. That was still broblem in my sisters husbands 99 modell ST2... I fixed it also.... :laugh:mrinflux wrote: modern ducatis come w/ a much better rectifier and no longer have rectifier issues.

What you think about Electrex RR51?
Stay in that original Ah value (16Ah). Its yours choise, what brand you buy, BUT remeber to check POLARITY of plus and minus poles, that they are in same side, as original battery have and surely right cable connection systems also in new battery, cause they made huge amount of 16Ah batteries, but conections must be, like original have! Many variations in those connections. Surely same sizes(dimensions), that there is enough space in battery box for that new battery!don_zielke wrote:WOW!This should be a sticky (or in the FAQ). You guys are awesome!
Can I just look for another 16 and hope it fits the battery tray
I've seen on the Electrex website that they sell the RR51 for E. 85,00 VAT and shipping included.Finnpaso wrote:Simply best quality/price ratio !persempre907 wrote:

That is MAIN point with Ducatis ! :laugh:
