pertronix with 8 volt battery
 

Hello anyone running a pertronix 6 volt positive ground with an 8 volt battery

For one with a user-name such as yours, I'd think you'd know that Petronix doesn't like under-hood heat, and an 8 volt battery is a band-aid for poor wiring.

couldn't agree more with the remark about poor wiring.

my car had an 8v battery in it when i first bought it. it wasn't running. after removing the 8v battery and the ruined voltage regulator and solenoid and the, get this, 12v starter and replacing it with the original 6v starter that was fortunately still in the trunk, and then replacing all the battery and starting system cables with#00 copper wires, she cranks over and starts up as well as any 12v car i've ever owned.

Contact Pertronix about the 8 volt system. They should give you the real facts. But ditto on the wiring. An 8 volt battery is needed because something is not right and needs to be fixed.

just my 2 cents but 8 volt is just a coverup not a cure [bit like painting rust] 6 volt works fine when its all good and correct and the old tale of shit lights again somethings wrong these days with 6 volt alts and leds don't know why any one would change to 8 let alone 12 v Here's one to think about changing to 12v can actually cause the dreaded dash fire not because the conductor cant handle the voltage/current but the insolation actually breaks down and leaks to earth

I would not be heading out west in my 33 with that stuff, 6v and points works well.

Get rid of both.

A 6 volt generator will never adequately charge an 8 volt battery unless your voltage regulator has been adjusted by someone who has the equipment and know-how.

Take the time to make sure all wiring is in good condition and all electrical connections are clean and tight; especially the grounds.

i agree...

although not sure the standard generator couldn't charge an 8v battery (it will put out various amounts of voltage AFAIK), but a standard voltage regulator sure wouldn't let sufficiently high voltage through to do the job. the one in the old ford i bought, that initially had an 8v battery installed, had a regulator that had been tweaked just a bit too much (like Meg Ryan's face), as it was letting about 11v through! waaay too much for an 8v battery...it burned out at least one gauge and the points. smh

Re: pertronix with 8 volt battery
 

I'd have to agree with most, a fully charged 6v battery with good cables will work as good as any 12v car.
Think about it, this is all there was and there were millions of cars operating just fine.
