2002 Audiovox SPS IM-200 in-Dash Radio
When I purchased this 2002 Daybreak I noticed that the radio didn't work.
Today it warmed up enough for me to venture outside and play with it awhile.
Radio simply doesn't turn "on".
On the rear, the 10-pin electrical connector has mostly speaker wires, along with GND, IGN, & BATT connections.
The IGN-wire is a short pigtail that terminates in a wire-loop that looks like it would connect to an old-style glass fuse.... there is another similar metal loop on one of the main harness wires.
(maybe someone shattered the original plastic fuse-holder?)
If someone with a similar unit could look under the dash with a mirror, at the rear of the radio you should be able to see the IGN-pigtail wire .
I believe it needs the IGN line to be +12VDC when the key is on, or when the shorepower is connected... and I get it in neither condition.
Assuming there is supposed to be a glass fuse inline with the IGN wire, there is nothing that indicates what the value of the fuse should be.
I checked the fuse panel and nothing is labeled for "Radio".... pulled all the "instrument cluster" fuses in the passenger compartment fuse panel (10 & 14) and they looked good.
Frustrating that it is going down this rabbit hole.
