I recently purchased a 1997 Mitsubishi Mirage from a coworker. Low mileage at 93k miles, in good shape mechanically, and purchased with a complete set of maintenance records. Its radio was not working when I bought it.
I purchased a low-end radio/CD player manufactured by Dual, along with a wiring harness, and installed the radio. I disconnected the negative battery cable to install it, but then reconnected the cable to test the radio.
I had made all the wiring connections and successfully tested the unit while the radio was sitting in the passenger seat. At that time, the dome light was on and I presume the instrument lights (for speedometer, fuel gauge, and temp gauge) were working.
Then, when I pushed the radio unit backwards, along with the assembly of wires, to secure it in the dash. At that time, the dome light went out, and the radio was no longer receiving power. I checked the 10-A fuses for the radio and the dome light (two separate fuses, joined by a plastic clip), and it was severed. I replaced the fuse, and now the dome light and radio are working fine, but the instrument lights are out.
The instrument (gauge) lights are on a separate 10-A fuse, which appears to be in tact.
Can anyone suggest what might be wrong, or how to troubleshoot this issue? I can borrow a multimeter, although I don’t have immediate access to one.
