Hi all, Yesterday was a sunny day, just a perfect day to ride the XS. Unfortunately, after a few kilometers at about 70 km/h (less than 50 mph), without using lights except in tunnels, the bike stopped, just like the other time. With a full charged battery and a brand new R/R, I must realize...

Hi 5twins, I am aware about the difference between AGM and Lithium/Ion. In my situation, I just wondered what should happen if I was setting the old battery... that has probably reached the end of its life. I hope September will be fair, in order to have some rides. And as usual, I will keep...

BREAKING NEWS ... BREAKING NEWS ... BREAKING NEWS Dear fellows, I read somewhere that new R/R did not complied with lithium/ion batteries o_O One of the first thing I did before the big issues occured, was to change the Pb battery and buy an AGM liquifix one. So I decided to replace the former...

I measured very low resistance on the outter slip. I leave for eight days next week and will work on the bike when I get back.

I connected the old regulator but the result is the same => nothing

Thanks Jan_P. I will first connect the old regulator (impossible with the rectifier, because of the dead connections)

I like all your posts, thanks. I measured the brown and green outputs as Jan_P asked. I switched ignition ON and the brown wire (out of the R/R) gives 12.6 V and the green gives 12.3 V We are still OK that I don't need to care of the white wires order, between the rotor and the plug. So I guess...

Many thanks Jan. Il confirm that the R/R I bought is a pre-80 and that the wiring of my bike is a mix between 76 C and 77 D. I also confirm the R/R I bought is exactly the same that the one from ELECTROSPORT (ESR350) and also the same that is sold by xs650shop.de. Here is the website on which I...

Thanks to Jan_P and 650Skull. Why are the user manuals not written in French, ah ah. I will try this, i.e. connecting the green wire to the black wire (if I understand what I read). I printed the 4 pages "fault-finding flow chart" from the ElectroSport website and I am afraid of what I read.

Thanks Jan, I feel sorry to be so uncapable. I post some pictures. I am ok with the connector that gathers the 3 white, the black and the red. I am confused with the wires coming for the "old" regulator i.e. 1 black, 1 green and I brown. I don't understand why I should connect the brown to the...

The ref I ordered is OK, according to the Yamaha ref. Do I have to follow the schematic I join, i. e. plugging the brown wire on the red coming from the battery?

Thanks jetmechmarty, the remaining problems are brown and black wires :(

As I expected, it does not work... The only question I have is : does it matter to connect the white wires at the exact position they were before changing the plugs, or can they be mixed between them? I unplugged the 6 pins connector and measured the resistance with the ohm meter calibrated M...

It's up to me!

Thanks for the so many replies. I ordered that on an Europe representative of a US supplier (as far as I guess) website. I should receive it within the end of the week. I will keep posted.

I read that there are about as many opinions there are members on this forum, ha ha ha. I am not so good for mecanic and worse in electronic matters. I will seek on the internet (european websites) in order to find the graal.

Now the question is : do I have to replace the dead rectifier with the same item or with the so called rectifier/regulator. I will browse that incredible forum to find the answer ;)

Today is a new day. So I made the slap test once again, with a very thin gauge and it worked! So I cleaned the copper slips as well as I could (sand paper and brake cleaner). Then I went to the rectifier and the connector was green from sulfate and one ot the pin is loose. It can explain why the...

Hej Jan_P, thanks for your reply, I will do so.

Work in progress. The voltage test in pictures. I switched the H4 headlight bulb for 20 min. low beam.
