John FYI -- from a recommended book:
Mobile power. It is tempting to use the cigarette lighter plug for 12 Volts to power the mobile radio and this may work for low power units, but it is always best to run two heavy gage wires through the firewall and directly to the battery via fuses in both lines. Don't use the chassis as a ground return, ground loop problems and noise pickup may occur, run both + and - lines to the battery. FM mobile transceivers with 50 W of output power can draw up to 10-12 Amperes of current at 12 Volts. Most cigarette lighter plugs cannot handle these high currents. Operating a 50 W mobile transceiver from the cigarette lighter plug may cause permanent damage to vehicle's electrical system, and can also be a fire hazard. You can probably operate a 6 W handheld transceiver from the cigarette lighter plug, but not a higher wattage radio. ============================================ "John LeMay" wrote in message news ![]() I recently purchased a used rig and along with it came a nice cigar lighter adapter that terminated in two "lugs" with screw on caps for attaching the power cable of the rig. There is no cord on this adapter itself. Anyone know where I can find a couple more of these? They seem ideal for running moderate powered mobile rigs ( 50W ). thanks! -- John LeMay kc2kth Senior Technical Manager NJMC | http://www.njmc.com | Phone 732-557-4848 Specializing in Microsoft and Unix based solutions |
