I am new to this site. I am planning on installing an AC inverter in my 2005 Impala (former police car). Unless someone can point me to a source of 20-30 amps inside the car I plan to run a lead directly to the battery. So my question is can anyone point out a good access point in the firewall to snake an 8 or 10 guage wire thru?
I am sorry for my spelling. I have been a poor speller all my life and at 55 y/o now I don't think I am going to improve much. I depend on the spell checker in my computers. But I am not home this weekend and I have a small netbook with me and the version of outlook installed has no spell checker.
Back to my Impala, thanks for the help. I just went out and looked at the firewall. I see the grommet that is used to pass a harness of wires. I also looked around and I also found a rubber plug in the firewall. I have to get a jack and lift the car to reach the engine side of the firewall and see what works best for me.
I also found a power drop in the trunk on passenger side behind wheel. I have a little concern of the power drop with that long run.
My options that I see now are to put a battery box in the trunk. Then a high power diode between that trunk feed and this second battery (with 2 fuses) to keep battery charged. Then I would run a power wire with a solenoid controlled from acc to power inverter. BTW I would use a body ground on this second battery for charging and both a + and - wire from the battery to inverter (fuse on + side).
Or I may run both + and - leads from battery with solenoid and fuse via firewall directly to inverter on floor behind drivers seat.
I have a few inverters here with the largest being 2000W ac output. If I go with the extra battery I would have the option to use any of them. I could also put a second solenoid that would parelle the diode with a momentary switch on dash that would control it. this would give me an instant jump if car battery was dead. OK I realize I cant do that as the trunk drop would never handle the power to start the car.
Thanks to everyone for the help
p.s. I see that I am posting on the web and not using outlook, but I do not see option above to spell check, sorry again
