i need some pictures of the grounding points on the idi engines. i have one thicker black cable bolted on the back of the block but don;t know where it routes to. the two in the front of the block go to the batteries, what about the braided ground straps off the firewall where do those go?

 

anywhere on a non painted surface of the engine block.(on the back is the cleanest)
may want to hit one the of head accessory bolts with sand paper.

2 grounds from battery on the front of the block, on either side
engine to chassis
engine to body
body to chassis.

electrical current does not care how its bolted, just as long as it gets ground to everything.

i go overboard and put 0 gauge for all my grounds.

 

^^^^x2 on all the above, especially on sandpapering the contact points and using heavy guage wire

 

I have a ground strap from the cowl to the hood???

 

Probably for an under hood courtesy light.

 

That's what I was thinking but there is no light. There should be a sticky or something in FAQs about proper grounding and locations.
