Pioneer AVIC-F700BT Problem

[PaulSeales]

Steve,

My Dad and I cut the main earth to the head unit tonight and ran a seperate wire from the connector to a new earth. Funny thing happened when we grounded it. The wire sparked! It seems to be getting a back feed from somewhere and I've no idea where.

What do you mean by main earth?

[chitowndad]

is main earth = ground?

Anyone else out there an electronics expert? Is your ground wire a power source?

[PaulSeales]

Sorry Steve - main earth = ground the thick brown wire in themain HU connector.

Paul.

Paul dont forget to do the update for your F Series.

I have the Avic-F90BT. The boot up may be a little slow but the F Series is awesome!

Trigem2K,
Does your avic F series have only one pre amp output? Do you have any ideas for Paul?

Paul,
So I'm thinking that your connector isn't correct. Is the Avic Ground wire in the right position that matches up with the brown ground? I'm wondering if you've got a hot switched wire connected to the ground and when you touched it to the frame, it's sparking. Try an volt/ohm meter and check the volts on the head unit. Touch the + to the meter and negative to a metal source.

I'm surprised that the other guys on the forum have no ideas on this issue but you've definately got a ground issue.

Paul,

Pioneers RCA Outputs are known to cause whinning issues. Try this...Take a strand of electrical wire, tie it around the connection of the Male/Femail RCA cables and GROUND the other end of the wire. This MIGHT cure your problem. I had to do this with my Avic-N2 when I had it.

Chitown,

I am not sure if the 700 and the 90 have different connectors. I would think that they both have Front Rear and Sub RCA outputs...

The version I have is the F90BT which is from Pioneers Premier line.
