That round ring thing with the cable looped thru it that's then zip-tied to the module is an after market Ferrite Choke that's been added/installed after the Spyder's left the factory by someone, probably after they'd experienced a few DESS issues, in an effort to try to stop any spurious signals over-riding & swamping the DESS signal between the antenna & the DESS Module; or maybe it was done in an effort to lessen the chances of the antenna itself being swamped by a stronger signal &/or to iron out any possible spikes in the signal..... :Originally Posted by GearHd
Doing this Ferrite Choke thing was one of the earlier BRP suggestions/attempts at fixing the DESS problem, altho it' since been revealed that doing this didn't seem to work too well &/or at all for many tho!!
It seems the only 'solutions' to the DESS stopping you starting your Spyder randomly that might be available atm are for you to replace the various Modules as & when they fail or as DESS problems become too much of a bother, but be aware that if you do that, you're only ever gonna be replacing the original dud items with exactly the same items that are still very likely going to experience this failure again/eventually; or you can see if you can find someone to Disable the DESS & then never worry about it again!
