[TECH - ELECTRICAL] A question about Grounding of Wiring

[txrocco@sbcglobal.net (ATS - Patrick Bureau)]

Thank you Tberk,

I use a size "0" battery ground, from battery to main chassis ground, from
Coil bolt to Valve cover, from main block to alternator.
the wires I was thinking or relocation are actually going to be bolted to a)
the main ground b) coil ground.

I will make sure all works out later once I have the engine back in, but I
used to have 13,45volts on my guage, I think after I am done the result will
be very similar...I will keep y'all posted...

=>One of the reasons manufacturers do things the way they do is to

=>so. If you engineer a combined ground buss you can reproduce the wires
=>wherever you want.
=>
=>Consider taking a big ol' honking cable from the battery post to some
=>spot of your choosing, tie it into one of those buss units the big
=>radio guys have and tie your device grounds into that. It could even
=>be in the cabin somewhere.
=>
=>In any case, clean and bright metal, coated to prevent future
=>corrosion and nice tight connections will serve you well, where ever
=>you connect.
=>
=>Lastly, if you will depend on these chassis grounds you will want to
=>provide for a good chassis to block to battery connection. Replace the
=>existing battery strap with a large gauge cable to the chassis and
=>block. Make the electricity think it's all one big block of metal.
