I wouldn't know, it was on there when I bought it.

Hi all,


Eventually I have had my carbs ultrasonically cleaned, so if should run fine now. I have made significant progress in the build and am almost ready to fire her up for the first time.

One question I have not been able to anwer myself, it is one for the electronics geeks among us:

- If I were to remove the battery/charge light, would the battery then still charge? I have heard a rumor this may not be the case, and the wire going from the charge light negative should go to the V.reg to enable charging. Anyone know whether this is true?

Apparently they don't charge if the light burns out - so the light needs to be in the system.  I think the resistance needs to be correct too.

I believe SED's correct ^^

When on holiday in Austria last summer the v65sp stopped charging, some diagnostics revealed that the battery charge indicator light didn't light up anymore when switching on the ignition. Changing this light to a working one also fixed the charging issue.

You can check it's functioning with this wiring diagram;

On the big block Guzzi's a common mod is to wire a resistance parallel to the charging light. searching this on the forum should show a few results. I don't see any reason why this wouldn't work on a small block.

The charge light is a vital part of the old Bosch alternators but you can replace the lamp with a resistor, 120 Ohm 1 Watt would be a place to start.

Interesting.... I should note my V65 has the "newer" charge system design, with no separate rectifier and regulator, but the later type regulator straight from the alternator.

Would this still apply then?

If your V65 Florida has a Saprisa or Ducati Electronica charging system, then the warning light doesn't need to be working in order for it to charge.

How do I find this out?

Maybe just try it with the charge light removed... If it does not charge I know where to look :thewife:

Remove the alternator cover and look at the alternator.

So it seems I have a Saprisa alternator. No charge light required then?

After riding for the first time last weekend, I can confirm:

- No charge light required for the Sarprisa alternator, she charges fine at 14.5v
- The Ultrasonic bath and choke-plunger-to-manual-conversion have cured the one cilinder dying on full choke when cold. :bow:
