Engine to Chassis ground?

[IgnoreMe 5,000+ posts]

those are pics of my alt, and my question is will that black bracket do anything as long as i have it and the bolt down to shiny bare metal?

i would take that bolt out, get a ring terminal to slide onto the bolt, and then put bolt back in with the ring terminal touching the alt and the black bracket on top. then just run to the chassis, if you want, or go to the batt negative (which is what i would do)

believe it or not, electricity flows from negative to positive //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

I'm just curious how much would flow over that engine ground that would make a frame ground insuffient if used.

I agree on most vehicles its probably just as easy to go to the neg terminal, just my curious self asking questions //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

if the alt bracket is about 3 feet from the neg terminal is that ok?

F150?

ya its a f150....

so the ring terminal should be between the alt and the black bracket and not the black bracket and bolt correct?

oh im not saying the chassis wouldnt work or is insufficient, i just always try to go straight to the battery negative, because you cant get any better than that. i like the piece of mind.

i have used the chassis before, and its worked fine //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif.

thats how my engine to neg is attached. just an alt bolt

1) alt positive to battery positive
2) battery negative to chassis

3) alt bracket to battery negative

many people do 1 and 2, and then for 3 go engine block to chassis....why??? i mean really. just go from the engine block (ie, just take an alt bolt out, put the bolt through the ring terminal, and bolt it down again) straight to the negative terminal of the battery. why use the chassis, when you can get the best possible and most straight forward connection by going straight to the battery neg? i dont get it.

I just do #1 and #2.

I don't see the reason for the additional ground unless you upgraded the ground to the alt itself.

thats exactly what it is. an upgraded alt ground since the alt's case is it's neg.

Interesting to know. I didn't know that.

I guess depending on how your engine bay is configured, it may be easier to ground the alt to the frame vs. grounding to the battery.

if you're going from the batt to the frame, then frame to alt, why not just go batt to alt?

as mentioned, the alt case is the ground //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Distance. If the distance to the frame to alt is shorter than battery to alt.

Just to follow up here, the battery to alt helped sigificantly. I wasnt dimming or anything, but the ODO/Gear Selector was "pulsating" going from neg batter to a bolt on the alt bracket helped. I highly reccomend it.
