I have a Gsl-se with some electrical issues it melted my( + ) metal terminal . I replaced it with a brass one and a new alt. New battery. Still no start I only get about 8-10 volts on the dash( my cheap muti-meter reads 12v @ the battery post,alternator,coils,main fuses). I believe it might be a open circut. What do you guys think?

 

Bad grounds?

 

that would be my guess also. Also have the starter tested at the parts store.

 

melting = high current = short = blown fuse/melted wire/fried component?

 

Ima check the starter and might change the battery cables next. Nothing appears to be burned no relays or fuses.. The lights, cluster, overall components work well. If I change the battery cables were do I ground them? If IRCC ive heard to ground the battery to the engine&body and the ecu to the chassis. Can anyone comfirm or correct me if thats wrong?

 

+1; you had a high-current short, it melted the battery terminal (which likely took hundreds of amps; they are robust) and at least one other thing, which is now acting as an open & preventing current flow.

HOWEVER, if you are only getting 10v from the battery, it's either discharged now or you have a bad ground preventing the panel from reading properly. Even cheap multimeters are pretty reliable within a few tenths of a volt.
