To Those With Trunk Mounted Batteries...

[ScottVA]

I have a 65 Belvedere and I want to relocate the battery to the trunk. Where did you run your cable...inside or underneath the car? If you ran it inside, where specifically did you come through the firewall and where exactly did you run it through the interior? Thanks, Scott

You are going to get a difference of opinion on the routing of your cable, but if you do an advanced search on the upper right hand side of the page you will find some interesting reading on the subject. Good luck, Al

Here is some more info. for you.

This can be a great thread. The Timskelton info is good. I used madelectrical a tried his rear mounted solenoid idea. I mounted the starter solenoid and the fuel pump relay on a panel in the trunk. I ran the 1/0 starter cable along the right side sill inside to the fire wall then across to the throttle cable area then forward to the starter. The alternator feed is a 8 gauge wire that follows the starter cable to the throttle area then up to the multipin connector area to the alternator. The 1/0 starter cable in only hot in the start mode. NHRA also requires a fire wall behind the seat and a external battery cut off switch. So far this has worked very well. http://madelectrical.com/index.shtml DCR

I used the MAD design on my '66 - I love it and have never had a problem with it. I use a ST404 (Ford) starter relay, I ran the + batt cable thru the truck floor at the top of the axle "kickup" then underneath on the drivers side. Instead of fusible links for the Alt and "power" circuits I used 1980's Honda car fuse holders on a panel next to the battery. the fuses are little thin wrench shaped metal - really cool. I also mounted a Volt gauge on the panel along with the start, fuel pump relays and fuse holders (so I could monitor batt voltage)

CD relay to kill alternator charge line
Starter Relay to keep main cable cold except when in start mode.

More wire to deal with, a lot safer than the nhra minimum standard.

Some run it under the car and some run it in the car. My brother runs his under the car on his race cars but I ran my cable through the interior on my 63. I went through the firewall sorta below and to the left (drivers side) of the master cyl. then under the carpet and along the rocker panel mld under the carpet and rocker mld and then under the back seat to the battery.I did not want the main battery cable to the starter hot all the time so I use a Ford type starter solenoid in the trunk so the battery cable to the starter is only hot while cranking. Then I run a 10 gauge fused wire from the battery to the starter relay on the firewall where the rest of the car picks up its 12 volts. Ron

If you look real close in this pic you can see the red battery cable come out just below the master cyl and a little towards the drivers side fender. Then you can see it turn and go inbetween the header tubes by the last (#7) plug wire. You can also see it just behind the the top of the shock stud. Its the best pic I have right now so I hope it helps you some. Ron

Here is an older pic I found from when I had my old eng in the car but you can see the red battery cable much better in this pic. Ron

Pay no attention to the other red cable you see behind the valve cover as thats my shifter cable.
