Hi All thought I would throw my 2 cents in about alternator conversions, very little downside in reliability , performance when compared with a 6 volt generator system, generator is ok but a tractor will struggle with it here in the North in winter with the cold unless it is in top shape
many of you know I work on cubs full time every day, working tractors they want easy/reliable, do not care about being original, for years I have used the Delco 10 units which have been around since early 70's , good, reliable, inexpensive and easy to get, few years back they were even easier to to use with a one wire unit appeared on the market making life even easier, Napa I use to recent times but them for $ 60.00 few months back they are now over $100, still one of the best units out there. for cubs I make a new lower bracket modify the upper and pulley to fit the stock 7/16 " belt as the pulley is made for a 3/8" belt. takes a bit of work to make a neat job
past few weeks I had 4 tractors here for alternator conversions so I thought it was time to try out something different due to the rising cost of the Delco 10 unit
Decided to go with a "mini Denzo" unit, bought from 4 different sellers on Ebay to seen if there are differences in them
most cost was a one wire unit from DB Electrical, been around a while , bought from them before and service is good, this was a true one wire conversion, and the pulley was already for the 7/16 belt, easy install , worked fine off the bat cost $130.00
the other 3 units all were advertised by sellers as "one wire" at half the price, $55-$65 , all carried the same part #s on the box as the one from DB
The difference is the pulley is set up for the 3/8" belt and it does not function as a one wire like the DB unit did
To make the other units "excite on the back of the units there is a 2 plug terminal and one needs to have this terminal energized with the switch, so I just run a wire from the alternator from the alternator to the positive side of the coil, just a foot of wire is needed , the pulley is kinda fat on material so I just open up the groove on the lathe to 7/16 " for the factory belt, do not even have to change length , I used the factory brackets from the 6 volt generator, just drill the mounting hole from 5/16 " on the front mounting ear to 3/8", the top bracket is unchanged, just added a spacer and tat was it to mount it, easy as it gets, see pics, these minis are 35-40 amps and charge fine after minor mods. to me yes its worth the little extra work for the cost of buying the DB unit, so its up to whom ever doing this to spend more for DB or do the mods of the cheaper unit
I did cut the rear ear off the factory bracket to make it look better but not needed to work
DB for the one wire unit takes and uses a different regulator changed to make it a one wire only and the pulley change
the diagram shows the terminal that needs to be hooked up for the alternator to "excite"
the second terminal is not used, made for the "idiot" light, I use a spark plug wire boot on the top post for insulation
