Default Can too much ground be bad?

Just wondering if had my car in the shop To fix my headlight not coming on the right side. Turns out it was a plug that came undone due to not enough slack to the wires when the lights pop back up.

I had them install relays to the headlights and they went ahead an added another ground wire to my car. So it total 2 new grounds have been added to the car. Now I don't have interior lights when I turn on my headlights.

Too much ground wires?

Unless you're grounding a power wire it's rare that additional ground would be a problem.

Our frames don’t always make for the best ground.
You can actually benefit by running an additional ground cable from the battery ground, up to the front of the frame and one to the rear of the frame.

I will have to go back and check the fuse. My speedometer night driving lights were the first to go, but my center gauge lights still worked. Now non of the lights worked. Hopefully it's something simple like a fuse.

Just a note... when my tachometer lights went out first (not the center gauges) i noticed electrical smoke coming from the left dash side.

Even though our cars are old enough to smoke, they shouldn't because it's bad for their health.

Sounds like something may have shorted out when the relays were added...

Smoke coming out of the dash is definitely a bad thing.
No such thing as too many grounds.
