8N electrical help needed please

1. Does the wire to the ammeter need to be stripped, or does the ammeter act like an amprobe, and does not need to touch the bare wire? The new wiring harness has a normal insulated wire plus a plastic sleeve in this area. The old wire that I removed was very brittle and it looked like it may have been stripped, but I am not sure.

2. My resistance block has a fourth wire going from the lower terminal to a small block that has a glass tubular fuse. This small block is mounted directly under the voltage regulator. What is this for? (the other three wires on this terminal are: 1. the above mentioned wire that comes from the starter relay through the ammeter, 2. the key switch wire, 3. a wire to the regulator)

I appreciate all the good advice that appears on this webpage. I have my 8N almost reassembled after an engine overhaul. I hope it starts. So far there are no extra pieces laying around.

I just finished putting everything back together after a major engine overhaul. First crank, it fired but wouldn't run because the carb was not full yet. Second crank, ditto. Third crank it fired and kept running with no adjustments to the carb or anything else. I noticed one oil drip from the fitting on the bottom of the oil filter that I had just finger tightened. I fixed that and am back in business ready to cut some weeds. Once again, I appreciate the good advice that I picked up from this forum along the way.

I found out if I just search the archives, almost every question is already answered. But, I appreciate everyone's patience to keep answering anyway. Thanks!!
