Motorola Spectra A9 Remote Head Wires?

[repeaterboy]

Hello fellow operators.If someone could assist me with my question i would appreciate the help.I have just bought a Motorola Spectra with a A9 remote head. Im running the high power 100 watt uhf 450-482.Its going to be a home base setup with a 40 amp regulated power supply.What size inline fuse would i need for the red power wire? And what size fuses for the orange and green wires? The radio is supposed to do 31 amps on high. Thanks for any help.

The orange and green wires are intended to go to an ignition switched +12V source in a vehicle. One enables transmit, one enables the radio as a whole. In a base station, they can go to the same +12V source as the main power cable. Fuse them separately.

If you're new to Motorola, go to batlabs.com and repeater-builder.com for LOTS of good information.

I'm unable to find any fuse rating for the main power, but mine is fused at 30 amps.

Hello zz.Thanks for your reply.I shouldve checked the previous posts.Do you run 100 watts with that 30 amp fuse? Thanks.

Motorola specs a 40 amp fuse for the high power 110 watt units. Red wire goes to Battery or the output terminal of a master relay, Green wire goes to the same connection point as the large red wire (Motorola is adamant about this), and the Orange wire can go to either the same connection point as the Green wire or to a switched source if you want to take advantage of the HUB (Hang Up Box) options available in the RSS. The fuse box is OK for the Orange wire connection, but MotherMoto never approved connecting the Green to anything other than the same source as the Red wire. The connection diagrams on Batlabs are especially helpful.

the mobile installation manual says 3 amp for the orange and green, and thats what they provide with brand new radios
