Have you had the battery load tested? Might be good for some things but still not good enough to start Spyder. Just an idea.
:agree: Load testing the battery and seeing it stay above 12 volts under
ALL the testing
is essential for our Spyders - other vehicles might be OK with something closer to 11 volts under load, some might even get away with 10.5 volts, but our Spyders
NEED 12 volts or better under the significant loading that's imposed by cranking the starter at the same time as starting all the electrics!! :lecturef_smilie:
So your local mechanic or battery retailer saying they've load tested your battery and it is still '
Good' is
NOT a suitable answer 
You need to know if it showed as maintaining
12 volts or better under all/full load scenarios -
anything less is inadequate & lends itself to exactly the sort of thing you've described above csguru!! It might not be the sole cause of your issues, but without a good and fully charged battery providing 12 volts or better
ALL the time, you'll never know if it's the battery just not being up to it, or if it's something else!! :banghead:
Mind you, in my experience with issues like this (and I've seen more than just a few!!) 9 times out of 10 (or better!) it's the battery &/or its connections, terminals, or the earth points; especially on these older Spyders with their batteries under the seat and the main earth point that is easily stripped &/or otherwise compromised under there too! So get the battery load tested, making sure it's got better than 12 volts
ALL the time; check, clean, and tighten
ALL the terminals & their fittings/securing points, and then try starting it again; and please, come back and tell us what happens,
even if it works and you're good to go!
