Hi Paso members,

After change to Megasquirt on my Paso, I noticed in the log files from the box that the supplied voltage was lower than 12V, mostly around 11.6-11.8V. When I hooked up a small voltage meter and had it on the dashboard during runs I noticed that when I switched of the head lamp the voltage increased to above 13V which is good. I have upgraded the rectifier to a Shindengen FH012AA.

The original generator is stated to give 300W. Is it possible to upgrade it to a more powerful one, like 350W or even more?
What is needed to get it working?

Some Monsters have a 350W generator and I saw in some specs that some engines have a 510W generator.

Only option is to have the stator rewound as a single phase using different gauge wire and more turns. Every other option means a new stlyle crank with the stator end crankcase modified to accept the later style 3 phase stator

Hi,

I do not want to raise more questions but since I'm completely restoring my '89 Paso 750, I have 1 question on this topic.
What is the more sensible thing to do: e new (electrex) conventional rectifier/regulator or converting it to a mosfet rectifier/regulator?
I read the article but not sure about the advantages to switch to the mosfet solution (little more complicated/expensive).
I have the engine, frame, suspension, wheels almost ready and after mounting the Weber, the next thing is the wiring etc.
I'm going to make the improvements Gerhard sugested (relais for ligth and starter engine and improved mass wiring), I just want a reliable bike not a modern one.
Also Ansim talks about 300 W, why is that not enough?
Lights will use approximately 100 W so that leaves roughly 200 W for recharging and ignition.
Just curious ....

a Mosfet regulator will keep tighter control of your stator output and prolong its life. Can't say much about the electrosport brand. I prefer the Shindengen

Higgy,

But is it just plug and play?
I have 3 yellow wires comming out of the stator.
The item about it was a bit confusing for me, with the 1 or 2 or phase construction.

The Shindeng I have seems to work fine.
Regarding the fuel injection, the fuelpump takes about 1.7A and the injectors uses 2x0.8A and the MS box probably less then 1A. Perhaps the battery is about to give up.

When I changed to use H4 LED lights instead of normal H4 there was no problem with the voltage. It was above 13V during the test run.

Reason for asking is that I found this link a while ago:

the early ST stator (98 model)is actually slightly smaller than the 907 and used the same magnet
Better off having your stator rewound

I'll start with to check the charging system for any 'leaks'. Brad Black diagnosing procedure

excellent place to start, Brad knows what's up and is always very helpful

One thing I have become aware of with the shindangding-a-ling regs is that they have a voltage sensor wire which tells the reg what voltage is in the main power feed , not what is coming out of the reg , and this wire is supposed to be connected to the switched side of the ignition switch, now on the ole Paso , renown for volt drop issues if your missing a couple of volts at the switched side ( more than likely ) the reg will keep upping the output V until it sees 14.5v at the test point ............ which means the battery is getting that 14.5v PLUS whatever the drop is , so ( I am using one of these regs on my quad ) I have fitted the sensor wire straight to the + batt terminal and its all very good . If you are having over voltage charging issues try moving the sensor wire and see if this helps ..... and then fix all the bad connections causing the fault
