Re: Off/On Switch between Battery and Starter My sole reason for always putting the switch in the ground side is to avoid problems in the cable between the switch and the battery connection,and in the switch itself.I fixed two A's that had problems with firewall mounted switches.One had the cable pull out of the lug,it bounced around on the steering box and the starter,It made a bunch of arc welded spots.Another had the cable too tight and chafed through on the edge of the firewall,that one blew up the battery.No matter what side it goes on it will work fine,I just want to eliminate that extra trouble spot.If the cable pulls out,the switch melts,or something chafes the cable or grounds the switch it is no big deal.I don't know where trucks would have had them,I never saw any that had factory switches.The outfit I worked for in the 80's had mostly Cat equipment with switches on the ground sides.I put switches in all the Macks he had,all in the ground side.My 1963 Lorraine loader, Allis-Chalmers dozer,and a Cat D-6 all have them in the ground side from the factory.I have an 02 Bobcat excavator,Kubota powered,that has the switch in the hot side.But,the switch is 10 inches from the battery.I just can't see any sound reason to require them to be on the hot side,unless it is for uniformity.

Re: Off/On Switch between Battery and Starter I use the So-Cal Speed Shop off/on switch on the ground side of my cars. Costs about $30 and has a metal key. Had a plastic switch malfunction as well as the green battery connectors fail at the most inoppurtune time.
Brent...i consider the battery switch a low tech anti theft device. |

We have it there purely as a anti drain device and a safety switch - less likely to have an electrical fire while parked in the Barn, and when my kids climb in a play, the starter button doesn't make the car drive forwards if left in gear :eek:. |

Re: Off/On Switch between Battery and Starter Yep! 6V pos ground, cut out in floorboard between seat and tranny! Must be easy and quickly accessable. I use it every time I leave the car. I also shut off the gas under the tank.
The only fire I've witnessed was caused by the starter foot button coming loose and shorting to the post on the starter. No cutout almost cost them the car. All wiring was in top shape. Just forgot the jam nut. |

There is no point in having insurance if you don't wreck your car. When your battery to starter cable is routed and secured properly and the smoke is coming out from the gauge panel in front of the gas tank while you're cruising down the road at 50 mph it would be nice to reach down and shut off the battery switch and maybe prevent a fire.

Re: Off/On Switch between Battery and Starter Quote:
In the event of an accident the engine is probably off but the battery is still in the circuit without a cutoff switch And what if that object is laying against the hot post? You could shut the switch off and break the circuit. Caterpillar puts them in the ground cable! I guess we beat this horse to death because some people still don't get it Bill! |
Re: Off/On Switch between Battery and Starter Question ?:
In looking at the "Yeahs" & "Nays", if somebody already neatly installed a heavy duty cut-off keyed switch in his Model A, & he later decides to remove it, & to not have any type of cut-off switch, might he be excommunitcated for changing his mind? (Maybe more to follow next week.) |

Re: Off/On Switch between Battery and Starter When I bought my Model A I put a shut off switch in the hot battery cable between the battery and starter in case of a power draw when not in use. I also put a fuse in the generator wire as I own several Reo cars and they are fused between generator feed and power block. I know I sleep better at night knowing I disconnected the power cable. Lifting the hood is easer than removing the seat to disconnect the battery cable. And hopefully if I have a short while driving car the fuse will blow.
