Auto stores will have a longer bolt for the side battery terminals or
adaptor kits if needed. Use the right size heavy duty solder lugs for the connections. I looked up my lighter circuit and it is 8 amps -- so 8 x 12 = 96 Watts -- at 50% or so efficiency -- should handle a 45 watt radio -- but that is pushing it to say nothing of stray noise that may be introduced and a possible voltage drop. Also the cigarette lighter may go thru the ignition switching. Somehow on all my cars I find a grommet that lets me get thru the firewall without drilling.

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 While I agree, I'm looking for a portable solution to use in the 'yl's vehicle so I can run a decent rig without drilling. I figure 10-20W is adequate (I think the 1/4 wave antenna I have allocated for this use is only rated at 20W anyhow). In a small temporary installation like this I think using the lighter plug is good enough. Of course while on the topic, What's the best way to connect to today's side terminal batteries? I'd like to go from the battery's +/- in *my* vehicle to a small fuse block where I can tie in before coming through the firewall. Unfortunately I don't do a lot of auto wiring and firewall drilling! thanks! -- John LeMay kc2kth Senior Technical Manager NJMC | http://www.njmc.com | Phone 732-557-4848 Specializing in Microsoft and Unix based solutions |
