hi all sifu sifu....

yesterday i just install my ground cable....
first is that my car is old..
so originally.. if open lights.. the rpm will drop a bit..
but then.. after i install ground cable, also same.. :(
dono why like this..
maybe my cable not thick enough? ( i using like 16 gauge)

the point i use is ... 2 point at engine block..
and one point at firewall, another point at body near the headlamp.
maybe not enough point?

any sifu can help?
