I did check them by “feel” and they felt very solid. Even gave the screw heads a tension test to be sure none backed out due to vibration, etc and everything feels rock solid. Am noticing a slight bit of chalkiness on a few terminals so am going to disconnect each, clean, and reconnect.
This may be the key as upon doing this again this evening was able to get the compartment light to “flicker” which points to a ground likely unless the other 2 systems (bilge & horn) are on the same positive circuit.
**Update** Found 2 issues with the terminal block. While all connections felt solid upon loosening each (after disconnecting the positive lead on the cranking battery) I found that one terminal had significant corrosion on it and so I cleaned it with fine file to get a good “shiny metal to metal” connection upon reconnecting it. Second thing was that the jumper pointed out by JEH was not seated within the crimp real good and had a little “wiggle” in it which was only noticeable when the terminal screw was loosened.
Went ahead and cleaned each terminal post, replaced the terminal block “loops” on both ends of the jumper and also the corroded ground terminal post I found and reconnected everything and IT WORKS!
Great call JEH, that was the needle in the haystack I was hunting for!! Thanks a TON!
Thanks to BCB Admin here who contacted me and although closed for the Holiday week was willing to see if there might be someone who could contact me from the plant to give me some guidance which is phenomenal customer service; particularly for a second owner (me). Many thanks for the contact BCB and a special thanks to JEH for your help. Hoping that this thread helps someone else who searches on the title topic in the event that they have an issue like this.
