Hi Hans,
Glad to hear your SRF is back with you once again.
I think I have just had a similar situation to what you've experienced.
My SRF is 4 weeks old and only on 560km (350 miles)
I riding to work last week and I got 'Code 43: Isolation Fault' pop up on my dashboard and then the CEL came on.
The 'Isolation Fault' message disappeared after about 30 seconds and then flashed up again a few km later - after that I never saw the message again but the CEL was permanently on - even after power off/on etc.
The roads were very wet at the time (but it wasn't raining).
Like you, I didn't notice any reduction in power even though in the manual it says that if the CEL is on then the motorcycle will 'enter into a state of permanent torque reduction'
It's possible that because I was in Rain Mode I didn't notice the reduction in power as in that mode the power delivery is pretty calm anyway.
I put the bike on charge overnight and it charged without any issues.
The following day I took it for a ride up the road, it felt fine but and the CEL stayed on, so I parked it back in my garage and called the dealer.
I suggested that because I was closing in on the 1000km (600 mile) service I could ride it until then and bring it in on schedule (my commute is 84km (53 mile) round trip so it would only have taken about 5 or 6 days before I hit 1000km)
But the mechanic was too nervous to agree to that - I think because the SRF is so new they are being very cautious. He told me to get it on a van and send it to them
So the bike went off to the dealer for a check-up.
It was ready to pick up in 2 days.
This is the report I got given when they delivered the bike back to me:
Technicians Report
Plugged bike in and it brought up faults to do with isolation and charging. These faults have been removed and the bike has been ridden and the faults have not come back on.
We advise the customer to not ride the electric bike in heavy rain conditions and then stick the bike straight on charge. The bike needs to dry out slightly first before it is then plugged into the electrics
So basically, I need to let the bike dry before charging..
In most cases this is fine but if I was on a long trip that required me to stop and charge at a service station, then does that mean I need to park it undercover, wait 30-60min for it to dry and then start charging it?! Seems a bit silly to me. I'll end up spending ages at the service station!
To be fair it won't be much of an issue for me as 99% of my SRF use is to work and back so it won't be difficult for me to wait a couple of hours to let it dry before I plug it in.
So overall it sounds like I was a bit luckier than you in that it didn't need a replacement part - however I do wonder if the water is getting in somewhere then it won't be long before a connection shorts-out properly and I end up sleeping at work
Hope your commute to work went smoothly today...
