Worked fine. It didn't have a wiper motor and horn was higher! You don't get the benefits of electronically controlling the dynamo but it still charged ok. If you do this always have a spare set of starter brushes with you - a 6v starter on 12v eats brushes (1930 type starter)

The Ulsteroid is similarly modified, a £25 voltage control unit, a bit of minor rewiring and a 12v coil, job done! The Voltage control unit must be of a type which only allows 11A output, these are readily available from suppliers of old tractor parts.
Advantages to me, cheap and easy conversion to LED bulbs. The ability to run a tyre pump, navigators map light, phone charger etc from a hidden bank of sockets. In 20 years of sporadic use the starter motor has been fine running on 12v without any modification. Likewise the wingdings of the dynamo. We did have a charging problem on the Lands End trial, but that turned out to be a faulty voltage control unit. To put this into context, the car is now used for MCC trials, which involve 200+ road miles including running for most of the night. Whilst the 6v system can be made to just about cope with running all night, the additional needs of competition do become a problem.
