Re: (ET) Alltrax, key switch, and charge/run switch



The schematic you sent shows pins 9 and 10 connected to the power source (through a 1 ohm resistor & diode) before the key switch; it matches mine in this respect. I'm only speculating that this is done to preserve the anti-roll; does anyone know if this is true, and, if not, why it is the case?

thanks,

Steve

I don't use the antirolling feature much.  That's what the brake is for.  I
don't much like the idea of current going into a stopped motor, nor am I
keen on the use of battery energy for this purpose.

I don't know what the max voltage is, but Steve suggested that the 
on-charge
peak voltage of a standard ET charger would (or at least might) be too 
high.

I cheated and just told myself I'd remember to open the main disconnect
before charging.  In practice, over the years, I've accidentally left the
disco closed maybe twice.  No harm resulted either time  However, I use gel
batteries and charge to a lower voltage than most here (just under 43v).
