[QUOTE="tractorman414, post: 5974, member: 244"] Hi I am enquiring on this subject for my friend and Dorset Section member, Mostyn Phelps. Mostyn is in the process of fitting a Nippondenso alternator to his enclosed D twin. The label on the alternator reads AKD094 and the literature refers to it being for "forklift & other industrial application", the literature also uses the reference 1N254 Reg ND 12v. The control for the alternator is housed within the alternator casing. The data indicates an output of about 40 amps, but significantly 20 amps at 2000 revs, so a very desirable unit. There is no problem with running this alternator via a belt off a counter shaft mounted in the original dynamo location, the alternator is located where the D battery would have been, and the alternator rotation is counter to the engine rotation. Mostyn is also considering using a similar alternator on his C twin and this is where the problem arises. With the C carburettor location, the alternator must be mounted on the left hand side and hence the rotation reversed to that of the D. Advise so for is that the alternator cannot be made to work with a reversed rotation. We find this hard to understand and perhaps its more a case of they don’t know how to modify the unit for a reversed rotation. Anybody out there who can help, please Bernard [/QUOTE]
