thought i would move this..almost scared to touch it... i still have 12.58V on my rad. hose... so far i have grounded... pass. side head to ...batt. ground.(#4 cable) batt. ground cable pigtail to inner fender (screw w/star washer) driver side head to ...firewall (braided strap) starter bolt to ...frame (braided strap) digital gauge box...firewall (#10 GA wire) all lights with norm. ...grounding lug (stock) all relays to...inner fender (bolts w/star washers) tomorrow i am putting a #4 cable from the block to frame. thought about hanging a ...static strap... under the car. does anyone see where i need more ......
I assume you checked for voltage with the battery disconnected. Get yourself one of these http://www.mustangdepot.com/OnLineCatalog/Cooling/radiator_caps.htm
I, for one, am in a puddle of befuzzlement over this ordeal. :confused: I don't know if you have rubber dampers where you're radiator is mounted or not, but you might at least try an alligator clip jumper-wire from the radiator to the chassis just to see if there is a difference. Strange, in deed.
Sounds like it is time for a coolant flush.......I would change brands.....Something there is not normal!!!!
I think perhaps you are confused on how to read your instruments. You cannot have 12V positive from your hose. walk us thru your measurement tequnique please.
rad. has just been...cleaned...press. tested...primed...painted and new antifreeze. and a pic. of the testing...i am new with this stuff but i can't think of anyway you should get a reading from a ...rubber...hose.
Is that the pos terminal? if so, it is flowing from positive to ground. i just did this same on mine, with same result. you would need to put it on neg terminal to have a positive source on hose. in other words no problem. Blownmav's link says it all clearly.
Since when does rubber conduct electricity? I just went out and tried my car. I get 11.86 volts to the radiator itself, but the radiator hose shows like .01 of a volt and even then it's fluctuating back and forth between 0 volts and .01...
i have found many fords have this problem of electrolysis and I have also found this same problems on detriots and old cummins they get so bad that I have found the impellor on the water pump completely gone nothing there. I have also found the same on some fords. You need to make sure that its a good quality pump. I have found that using the cheaper products really increases your odds of having the process of electrolysis happen something in the make up of the metals. The reading on the meter is normal although they say that rubber is an insulator under the right conditions it will conduct voltage great.
