lyenga ronnie

My name is Ronald. I work in a mobile telecommunications company here in Kampala, Uganda. Am an ardent fun of Jawa 638 However, my bike has a problem with the wiring system It starts fine. From memory you push the key in hard to turn the ignition on and then turn it with it still pushed in to work the lights. First, the ignition key can only be left at 0 for the bike to move. So this means the lights will not work. But when you turn the ignition key to 1 for the lights to work, the engine goes off and the battery is drained The problem I have hear is that mechanics in Uganda are not well-versed with jawa technology The switch was checked for a possible leakage. All wiring in the switch works fine Recently a mechanic told me it could be a problem with the alternator and Tout Kindly advise. I have a feeling you have dealt with a similar case before Please also help with with a user manual or details of the wiring system that could be helpful in sorting out this problem
