Default Electrical issues need help

OK last night I posted about an electrical problem. Today I got the battery replaced and the car starts fine.

BUT something is wrong with the electrical aspects of the car. Sometimes the radio will work some times it will not, sometimes the AC will work and sometimes not work, the power antennae goes up sometimes it stays up after I turn the car off. Some times the speakers work other times they dont. Same with the lights behind the instrument panel.

So I know everything is in working order it is just a bigger problem that they do not work at the same time. This is very odd it is like my car is possessed.

Is there something I need to replace? WHat do I do? I need help there is no answer in the trouble shooting section of the manual.

It sounds like you have a loose power or ground lead somewhere.

Start by inspecting the battery terminals and leads and move to the grounds.

Check the wiring diagrams in your Helms to see where those non working items have a common junction. It's from that junction back to the power source (including its grounds ) is where the problem lies.

Did you check your Helm factory service manual 2 months ago? You cannot diagnose this kind of electrical problem from long distance unless someone spends a lot of time going through the manual for you.The manual has the electrical drawings in it and if you want it fixed I suggest you get to it.

Check all your grounds The manual will tell you where.
