I always remove my battery from the car for the winter. I remember reading that there is a definite order regarding polarity for disconnecting the battery. Negative first then positive or positive first then negative. Which is it? Last year when reconnecting the battery I fried my electronic ignition module! Thanks for your help on this one.

Wolfgang is correct in both his posts!! :-) It depends on which version of E-type you're discussing. Just remember to first disconnect the cable which goes to the frame/ground/earth. As I've commented before, if you disconnect the "Hot" cable first and your wrench touches a grounded point---much fire & smoke ensues.
Early E's like my '63 had a positive ground but the later ones were negative ground. Tom Hughes

Generally disconnect pos then neg. reinstall pos first then neg last when reconnecting battery in spring. Don't understand why you wound up damaging your ignition -- it is not absolutely mandtory that battery be disconnected or reconnected in this sequence. 1963 XKE coupe Owned since Feb 1970
It's better not to think of Pos and Neg, rather think earth/ground and feed. Always disconnect the earth/ground connector first and reconnect last. The simple reason for this is; if you touch the earth/ground terminal with a spanner and at the same time touch any part of the car, nothing will happen! On the other hand, if you touch the feed connector and any other part of the car you will get a very large spark,(in effect you have just touched the battery terminals together). It would appear that last year you connected the cables to the wrong terminals blowing a transformer!
