I had a problem with my air pump being locked up
corrected problem but some how lost voltage to it
The fuse is good for that circuit
Is their anything in that circuit that can knock out power to the air pump after the main fuse
car 1988 560sl
All other electrical devices work
At least I haven't seen anything not working
I am checking for voltage when car first starts also
First minute only
Any help would be appreciated
