Sudden Power Loss on L.A. Freeway

[billclemen]

Returning to SoCal from a trip up to RKA (the luggage folks) in Windsor (west of Sacramento and N of San Francisco) when I had 3 sudden power losses. Riding the speed limit when....sudden power loss......get over to the apron safely...calm down......restart the Spyder (X 2). The third time Spyder wouldn't turn over. I put it in gear, pulled the clutch in, pushed the magic button... and it fired right up. Continued on home, much more paranoid and cautious. I already had discovered that the main ground wire bolt had been stripped. Spyder had been delilverd new to me with this problem since no one had messed with the ground wire bolt until it was discoverd stripped up in Windsor. I was standing there when Richard attempted to loosen the bolt and it was stripped. So, there was no way to securely tighten the ground bolt and it had presumable been loose from day 1. I confidently assumed that this was the problem. When I took Spyder in to the shop they corrected the stripped bolt and I took off for home. Got about 4 blocks before it stopped again!! So, the sudden loss of pwower obviously wasn't the fault of the bolt holding the ground wire each and every time that the problem had happened. Got Spyder restarted and went back to the shop. This time they replaced a relay that they thought might be the culprit. I purchased a spare relay to carry with me and returned home on surface streets. Everything seemed to work just fine. They said that if the relay does not correct the problem they would do an extensive analysis. Hope that is not needed. They also said that the particular relay had been causing problems on other Spyders. Anyone else had this sort of issue?

Typically it is the relays... there are three up front... swap them around. Symptom... dash lights up with every warning known to mankind. Did yours do that?

No warning lights flashed. Just sudden power loss.

When you're talking about the 'main ground' bolt are you talking about the one you can see when you pop the seat up - on the non-clutch side ?

If so, that bolt doesn't just go into the frame - it has a nut underneath - so you have to remove the panels and have a wrench on it when you tighten it. So it it appears to be 'stripped' you are most likely just spinning the nut on the other side.
