Hi, i have just bought a 6v solid state regulator from mz parts bristol. It came without any instructions, so i queried whether i needed to remove the adjustable resistor from the dynamo. (A friend did this conversion on his bike after purchasing a regulator from a different source and was instructed to remove the resistor). I was told i did not need to remove it.
I fitted a voltmeter and noticed the charging is very erratic with wide variations of voltage at the battery. A friend who is electrically minded thinks i need to remove the resistor. Has anyone come across this problem? regards, John
