Thanks @BumbleBee for the reward/medal?
@Wesley.....we refer to some okes as keyboard warriors in fly fishing. They are experts....in sitting and typing the whole day and not doing a lot of fishing, they also tend to hammer guys who actually catch fish, must be jealousy?
That's quite typical of the internet in general, to be honest. Fortunately we are blessed at this forum, it's like big family over here - only friendly faces!
Regarding your question on the battery / coil, suggest you post in the Newbie's Corner, you will likely get more help there as your question will be crowded out in this thread quite quickly.
