A Big Three Query

[jhnkvn]

Personally, replace the whole thing if you're already doing it and replace it with 4AWG. Hindi lang naman yan sa matter of kaya or not.. but it's a matter of optimizing the flow of electricity by reducing resistance. Will it cost more? Yes. But chances are if you already done one or two of the procedure, doing everything won't hurt your wallet.

Just remember to make sure everything's connected and installer properly.

I already got the items needed kaso hindi ko ma determine yung positive line ng alternator ko. Three wires kasi siya then two wires are thinner while the one connected via nuts and bolts are fairly thick. I was thinking of going in a alternator shop para ma check nila and is it okay na wala ng fuse yung sa alternator positive to battery positive connection?

yung nakakabit sa likod with a large bolt is the positive one, covered by a red rubber grommet yun..
ito din ang pinaka malaking wire among the three na meron ang alternator.

dapat may fuse sir ang positive line nang alternator going to your main fuse line.

Eto po ba yung sinasabi ninyong positive ng alternator?

Kapag mag install ng Big 3 Grounding Kit ay di na kailangan galawin or mag add ng wire sa +Alternator or +Bat. Ground wire lang idagdag. Kaya nga tinawag na Grounding Wire Kit.

Hwag galawin yun +Alt wires. Ang important malagyan ng Ground Wire ay yun - Alt Terminal na katapat ng +Alt terminal. In between sa kanila yun white connector sa picture mo. Iyan ang best connection ng -ALT kasi kasama iyan sa casing ng Alternator - or gnd side. Linisan mo uli -Alt screw bago lagyan ng Ground Wire.

Hwag maglagay ng Ground Wire sa Bracket ng Alternator. Kung ganyan kadumi sa picture mo ang bracket ay loose connection din iyan. Magkaroon pa rin ng voltage drop. Iyun voltage drop ang iniiwasan kaya naglalagay or dagdag ng Grounding Wire.

WARNING. Tangalin muna +BAT wire kung may galawin na wire sa Alternator. Ang lakas ng Spark diyan kapag may nag short. Tunaw yun wire diyan.

So yung encircled sa part sa picture ko is yung alternator positive kasi may rubber insulation ito around the bolt that goes inside the alt case then yung may mark na "R" pwede kong kabitan ng ground wire connected sa battery negative. Tama ba.

sa BIG 3 included ung +ALT to +BAT.

sa 5-POINT, 6-POINT or 7-POINT GROUNDING KITS, puro GROUND points naman ang target.

example of BIG 3..



(1) -BAT to CHASSIS
(2) -BAT to -ALT (Mounting Bolt/Bracket connected to ENGINE BLOCK)
(3) +BAT to +ALT

Alternator Wiring

The ALTERNATOR BODY is both a GROUND and a heat sink. If you place your hand on an alternator bracket, you'll probably notice it feels warmer than other accessory brackets; heat from the diodes flows through the alternator body and into the bracket, which helps to absorb and dissipate the heat like a radiator. In the same way, electrical current from the battery flows through the ENGINE BLOCK into the BRACKET and, thus, into the ALTERNATOR. The positive output wire from the rectifiers connects to the battery's positive terminal, closing the circuit and keeping it charged.

"R" terminal is for the IGNITION switch.

Yun turnilyo na katabi ng R ay palagay ay -ALT Terminal. Yun R ay para sa Connector ng Relay. Linisan mo ng steel brush yun bolt para ma-confirm nga dikit sa bakal or kaha ng Alternator. Yun ang -ALT pagdikit sa kaha. Iyan ang the best Ground connection.

Para sa akin ang Big 3 Grounding connection ay:

1. -Bat and -Alt. For better charging of Battery, better dc voltage for engine electricals and Brighter Headlamp.
2. -Bat to Distributor casing or Cylinder Head. For better Ground connection to drive Ignition Coil. Resulting better spark voltage.
3. -Bat to Starter Mounting Bolt. For 1 click start of Starter. Starting current was very high ampere and needs very good grounding wire connection to avoid voltage drop.

Note: Purpose of Grounding wire was to avoid loose connection or voltage drop.

Do not removed original ground wires. Big 3 Ground was only for add on wire for old electrical of car.
