Hello, I apoligize in advance for the lengthy first post but here it goes. I am converting an "H" to 12 volts for my aunt. I read a lot of posts on here about the conversion but have some questions. I plan to use an Optima gel battery and will have to build a new battery box. It looks like width and height of the original box are OK but not the length. It appears it needs to be about 1 1/2" longer. Is there room to accomodate a slightly larger (longer) battery box? I will use a diode instead of the light in the alternator circuit. What amp rating does the diode need to have? I read these tractors were originally positive ground systems and the ammeter will read backwards which is easily corrected. How do you get the starter rotation correct? Some of the info I see is for the "M". Are the "M" and "H" electrical systems the same or close enough that the "M" info also applies? Will the standard pully on a typical alternator spin it fast enough to charge effectivly? I will take pictures and try to post them when finished. Thanks, Kevin
