Just an update. Appreciate all the info as info is knowledge which we most often can not have to much of. I do have a good knowledge of electricity. Checked my voltage at the plugs, was only 8.9. Started tracing wiring which was not all that heavy. Found a corroded plug in type connector, removed same and spliced existing wire. Cleaned copper bar and all connections at plugs. Rechecked voltage, now almost 11. Some improvement in starting. Disconnected the old wiring entirely, ran all new wire from battery, thru new 30 amp fuse/holder which I had laying around then thru new single pole (50amp) switch, eliminating the regular switch assembly entirely. WOW! Talk about a fast start. Realize this configuration may not be the safest but for the moment it's great.
