Hello all, I am new to the forum, but I've been lurking for a while now.
So, I have a 1978 GS550E, and I had it sitting all summer, with no real time to mess around with it, as I was taking a calc this summer and it robbed me of anything resembling a life. Anyhow, I had been power spraying it back in May or June when all of the sudden it died. My class started and I didn't really do anything with it up until this weekend.
I bought a new battery, as mine had a couple ruined cells, and was pretty much toast. I charged it, threw it on, however no start. Pull plugs, no spark. So I proceeded to jump down the rabbit hole at this point with ignition systems (studying biochem Engineering, but can't stand Electrical for reasons like today) I tested voltage on the battery, sitting around 12.9 V, or something. Tested the voltage from my negative battery terminal to the coil input wire (orange/white) at 10.5 V, so I scrubbed a bunch of contacts down the line, and got that voltage up to about 11.2-3 V. However, my coils are reading ohms ratings between 3 and 6 on the primary resistance, and 15k ohms on the secondary of coil (2,3) which is to spec. But coil (1,4) is reading an "Out of Limit" on the secondary resistance. So I spaced my points, and my condensers look good, I cleaned up a small amount of corrosion on my points, but nothing crazy, and now I have a weak weak weak spark.
So, my question is this; am I to be certain at this point that it is indeed my coil? Or should I start by replacing my points and condenser, cleaning my harness, and trying new plugs (which were pretty carbon fouled, but figured it could be a product of low spark)?
Excited to try and tackle this with y'all.
