As many are aware there are a couple of fuses that like to fail on the MC board. This happened to one of my Vectrix VX-1 scooters (blue 2008 model). So I managed to get the fuses (tricky bit to do believe me!), replaced the ones on the MC board and it works. These are the little black box fuses marked "GTT" 250V 40A on the motor controller board. Typically the two just below the negative terminal; you have to remove the cable to see them clearly. If the letters are brown (not white), then the fuses are fried, or about to be. This triggers the CAPCur error code on the dashboard (but not always!).
Seeing that other owners have had this issue too, I ended up getting extras from the manufacture and I'm making them available for sale. blah blah blah, fixed the bikes, blah blah blah... you know the drill.
Here's the clincher... The demand is increasing! So far I've sold 60 fuses. (people sometimes buy extras), but that's at least 15 scooters the needed repair.
So this is a little worrysome -- what is causing these fuses to blow up? My scooter's previous owner lived in a very hot region, some of the batteries were bloated, and he said he did a lot of regen braking just before the scooter died. he said the scooter was never opened up by anyone, so it could not have been improper ICL procedure when hooking up the batter, or was it? I see indications the scooter was serviced internally at one point. So was it an improper ICL usage (if any at all) that damaged the fuses leading to eventually failing?
Any theories? Sure it's good for the business of selling fuses, but that's not my goal. I don't want to have to repair my scooter(s) again, and I certainly do not want any other owners to have to buy/install fuses multiple times.
