6 Volt Belt Drive Alternator
Is there any source for a belt drive alternator available in 6 volts similar to what TTP offered in the past ? Converting a '15 Runabout off of 12 volts back to 6 with electric start capabilities. Thanks for any information.

Re: 6 Volt Belt Drive Alternator
Steve,
I put one on my '16.
It is a GM 10si type.
35 Amp, Grooved Belt.
I had to make my own mount bracket.
I will look up where I got it today and call you.
EDIT : I found it.

Re: 6 Volt Belt Drive Alternator
Steve, I think the new trend is to use one of the one-wire Denso 'mini alternators' that are popular in the racing world. These units can come with the serpentine pulley already attached. I think several T guys have bolted the main bolt hole of the alternator thru the driver's-side upper water outlet so the unit can pivot on that bolt. These units are around $100 and are brand new.
If you want to machine your own pulley, here is one...

Re: 6 Volt Belt Drive Alternator
Are they available in 6 volt ? I could swap out that mini for the full size Delco on my '14 - it's a 12 volt system.

Re: 6 Volt Belt Drive Alternator
Not sure if they are manufactured with 6v regulators but I believe I was told a 6v regulator was available for it.
The attraction for me with the mini is that it is compact and non-intrusive in the engine compartment. I would like to machine a pulley that would allow me to use a leather flat belt. I'm not sure if this unit only producing 35 amps means it theoretically has less parasitic drag over larger or higher output units, but since my T only has LED lighting and GPS draw, my current draw is very low anyway, maybe I can use a leather flat belt to spin mine.

Re: 6 Volt Belt Drive Alternator
I'm having 6 volt regulators made for the denso style mini alternators, they are due in the end of November. The alternator kit I make is listed on ebay https://www.ebay.com/itm/256142112941
