Hello, in my mill I still have the original 6V Bosch Noris ignition, also with the old mechanical F-controller. This did not work any more, I thought all about how it works and then set it as well (no – excitement about resistance – full excitement with contacts and anchor). This works quite OK but not good enough, i.e. in the normal speed range I have 6.5-6.9 V charge voltage, however with VOLLgas it goes up to 7.2 V and with stand-up gas under battery voltage 6,2 V. Therefore and understandably my 6V Gel AGM battery has now applied for the pension. Long speech short sense, I probably need a new electric controller (harm about the original condition but does not help anything). As I have to connect it and remove resistance I know. 1. How much heat can the parts (probably quite little) easily place it instead of the F-controller at its place. If he does not like that, must I guess I’m going to extend the cables and somehow take them out of the ignition, which would be a shame. 2. These controllers, cast out aluminium housing with PU/plastic resin, can’t be adjusted. Which charging voltage do they supply? I bought a new 6v Gel AGM battery, which should not break again (in case of load break in and can’t be charged anymore). I’m just an occasional driver with a few hundred kilometers a year with this machine. ipps, Best regards Peter
