VHF Spectra will not power up?

Post by flynsqad »

I am a newbie with a question regarding a dash mount vhf spectra I just picked up on ebay. Hooked everything up in a 2006 chevy tahoe, but when I power it up, nothing happens. I have found some great info here on batwing labs and am very interested in learning all I can about motorola mobiles for future purchases...please point me in the right direction...Thank You!!! :-?

First thing.

Make sure you have power to the accessory connector and that it is plugged into the radio. Probably the most common newbie mistake.

I'm happy that was the only problem, if not, I would have mentioned replacing the fuse on the faceplate, which will prevent power up if blown.

It's a 4 Amp rated cylindrical type with a white body-probably ceramic.

Where exactly is this fuse at?

Jackhackett:

It's on the board side of the front panel on the L/P spectra.

Looking at the faceplate from the rear, the pins are at the bottom and the fuse is on the lower right side of the board, near the outer edge.

I don't have one opened up here so I am going on memory.

It's about 1/8" diameter and just about 1/4" long as well, with 'silver' caps for solder adhesion.

The part you're describing is the 4Mhz crystal for the micro, replace that with a 4A fuse and I think you're going to have a dead control head ;).

The only fuse I know of in a dash mount Spectra is at the front of the command board, it's a green 7A picofuse which supplies power to the audio IC among other things.

You beat me to it Jack. Can't count the number of 'fuses' I replaced with the proper part on those control heads.. Sure looks like a fuse, and ohms out just like a bad one. Good info.

Brings back memories.:)
