After messing around a little more, I was moving around the wire to the pop-up resistor and the light went out. What a thrill! I had found a short. I kept moving the wire around and couldn't get the light to come back on. So, I'm putting it back together and will take it out for a ride, sticking close to home. Thank you so much for your help and patience with me. I'm thrilled to be able to ride again and learned a lot about dealing with electrical and about the bike through this process. I'm a little nervous to get stuck somewhere due to a short but, can't take having 60-70 degree days any longer without being on the bike.
Congratulations, you have fixed it even if you don't know what you fixed, what's your opinion of the light bulb method now?
I was an electrician/Instrument tech for 60 years, sometimes the simple lamps are better than an expensive multimeter. When I was an apprentice we had a 100 Watt 230 Volt lamp wired in series with a pair of probes on the bench for testing, gave you a nasty jolt if you weren't careful, I can't imagine being allowed to do that these days.
When you measured 1.4 in your previous post that was 1.4K Ohms surely?, 1.4 Ohms would give you 8.5 Amps at 12 Volts, or perhaps that's what blew the 5 Amp fuse, at least if it occurs again you know where to start looking.
Congratulations on your perseverance, your Electricians ticket is in the mail.
