It
might not help you any, but I'd strongly recommend that even if your Spyder's engine starts easily, you still do a battery load test before doing anything else; noting that because our Spyders are so power hungry that even if it is still capable of starting the engine, if your battery drops anything much below 12 volts under load, then it is very likely going to be incapable of starting
all the electronics properly/at the same time, with the DPS being one of the major and most power hungry devices on your Spyder; and because of that, if your battery gets too low under load, it doesn't necessarily mean it won't start &/or run, but it
will generally do things like displaying "... a multitude of errors, Limp Home mode, EBD, VSS & ABS and multiple lights on the dash..." and maybe even causing expensive failures in things like the DPS, the dash module, &/or the starter motor if you persist in operating the bike with less than ideal power.
Sure, you might think it a waste of time cos your battery 'looked good'; showed a 'full charge' beforehand; &/or was on a tender before all this started happening ('tenders' rather than battery 'tender/maintainers' are renowned for hiding dead &/or die-ing batteries), but you could be surprised - the number of people who've had similar issues with their Spyder when their battery was supposedly fully charged and in good condition juuust might astound you!

And if you go by the number of people who've been caught out by the 'normally accepted' definition of a 'good battery', which is if it shows anything better than about 10.5/10.7 volts under load, who then found out that their Spyder
REALLY doesn't work well/play nice with anything less that 12 volts from their battery under load, you may well be thankful for 'wasting' that time. More often than most think, problems like you describe come back to the battery simply not being up to the task!
And if your battery
ISN'T the problem, and it passes the load test with better than 12 volts under load, how much time have you really wasted?? Plus, you will have confirmed that it's not the easy fix
BEFORE you've wasted a heap of time &/or $$ chasing a problem that
could've been as simple as a flat/battery failure and a relatively easy/inexpensive fix! I find it helps a
LOT to check and positively exclude those simple things
FIRST, rather than just assuming it isn't the battery cos it was on a tender and so throwing shed loads of time and effort at other things when it really only ever needed a fully charged/new battery!!
So I'd strongly suggest you load test the battery before doing anything much else, certainly not anything that costs much (in time or $$) and look for your battery to maintain
at least 12 volts under load!
