A Big Three Query

[Chinoi]

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.

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.
