May I recommend that you make use of a test lamp, preferably a headlight bulb in a test lamp.
Easy to mock up your own DIY test lamp. Using a headlight, solder or use a spade connector to connect one lead to the bulb filament common and another lead to either of the other tags. (only one of the three connector tags is the common tag) It doesn't matter whether you connect to the high or low beam side of the bulb. It is the resistance of the headlight bulb that you are looking for. Any bulb with less resistance may not show up a bad / low restance connection or if a feed via a secondary component.
Connect one end of the test lamp to the positive terminal of the battery and with the other lead, check for a negative supply on the starter motor or an engine bolt. Next would be to pull a headlight connector and check if there is any common negative / earth at the healight commector. Each time the test lamp lights up, you have proved that you have located a negative feed from theon both the motor and headlight connector back to the battery negative terminal.
Once you have established that the neagtive / earth common is present, connect the test lamp lead to the negative side of the battery and turn on the ignition switch. With the second test lead start checking for the various postive feed points.
A circuit diagram would be handy to varify where you should be picking up a positive once the ignition is on. A circuit diagram is attached in reply #3 of

Please provide feed back on any progress or findings.
