I have a Fortress 4 wheel scooter that has intermittent electrical problems.
1. The key does not always turn on the scooter. I have to remove and replace the key to operate the scooter. When I insert the key, I can hear a relay click on but this does not always happen
2. When driving, the scooter may suddenly stop and then start again. Sometimes this happens based on how loose or how tight I press on the throttle.
3. When driving or standing still, the scooter may lose its electrical connections and the key needs to be removed and replaced.
