93 SC400 lighting woes

K gang, I have an annoying problem. The rear turn signals on my SC don't function properly. On a zenki SC there are 3 1157 bulbs across the yellow lens in the tailight. Well if I have all 3 bulbs in there, they won't light up instead the brake lights under me come on. If I run just 1 bulb, it works but blinks fast because there are two missing. I left the hazards on to test. The one bulb os bright, add a second or third and the filament only barely glows a touch.

I think the issue is something to do with series vs parallel but my electrics smarts are rusty. :oops:

The other issue is the rear light warning light is always on, but the 3rd brake light is missing so I will replace that and that should be fixed.

Sounds like a bad connection or ground
