Critique?

[MikeFleming]

Kinda difficult to read the small, hand-written (very neat writing, btw - better than I can do) notes.

Other than that, it looks great. Lots of straight lines, squiggly things and electrical looking things.

I knew I could count on you.

Looks discernable on the sheet of paper on my desk, not so much on the computer screen. I have to remember that we're all getting to be old duffers...even Meotch.

Bob must have used the CAD program on his new laptop to do that!

That's my kind of lap top!!!

Better?

[MikeFleming]

Why two (125A) fuses in the charging circuit? How large is the alternator output, peak?

Be sure to add normal stranded cable ground wires and RF braided ground wires to chassis form block (probably not needed form battery to chassis). And can I assume there's some other electronics installed into the car? Radio? EFI, data logging, brake lights, ...

Nice touch with the red.

[Meotchh]

Just as Mike noted, there is only a need for a single fuse within 19" of the battery to protect the battery from a dead short. Depending on the load on the battery I would opt to go with either a 125A or 150A.
Why the 1 or 0 AWG wire for the starter? That is alot of extra unecessary weight. The 4AWG would suffice for the current drain on that run.

Chassis GND should also be a through bolt design with star washers used under the bolt head & between the nut/sheet metal.

Power lug(s) should have an appropriate rubber protection boot or similar non-conductive cover to protect Bob from easily blowing shit up.

[Bob Holmes]

Can the charging wire be an 8awg?

[Bob Holmes]

Oh, I also went with a 140a circuit breaker instead of a fuse.

Good idea. Much faster recovery time.

[Bob Holmes]

I think I may have failed to account for the external voltage regulator.

Wish me luck, I'm diving in head first this weekend.

Have you notified emergency services in your neighbor? Don't forget the pics and the disclaimer giving Mitch credit!

[Bob Holmes]

Emergency services is on speed dial, and I know all the urgent care facilities within a 30 mile radius. Just to get ahead of the game:

Without Mitch's advice and flying down to connect the final wire, I would not have been able to start the car.

Good got that out of the way.

I've altered the battery hold down that my son worked on so that it'll serve the function intended. I'm getting ready to run down and buy some welding cable in order to get the ground to the block and the power to the starter finished. My Summit box with various cable boots and wiring loom covers already arrived. So far so good.

Tomorrow I'll probably go to the JY to snag a Mark 7 fan, some relays, and what ever other kind of paraphenalia I think I need. I'll be on the look out for a 95amp small case alternator.

My son kicked butt right along with me today. He did a great job of pulling parts that I needed off the dead Hoser. I think we got a good chance of making some excellent progress.

Barring any trips to the Emergency room.

Bob - I will be standing by the phone all weekend - in case I'm needed.

( Do not call during nap time. )

[Meotchh]

Can the charging wire be an 8awg?

NO. If you are running 4AWG then use it for charging as well.

[Bob Holmes]

Bought the welding cable last night. Unfortunately the buddy that I thought had the cable crimper can't locate it. Damn.

So I've got to go down to Stockton and buy one from Battery Bill's. These side trips are just time killers. Double Damn.

I did get the hold down reconfigured so that it will work. My son worked hard on it, but first time fab work frequently needs some tweaking.

So today's big push is to get everything located, and all the cables run.

I picked up a new starter. I had a nearly new, lifetime warrantied autolite that we wore out on the racecar. I don't know if you guys remember, but we had a problem with tooth mesh on the flyweight flywheel and we were wearing out starters and breaking bell housings until we figured it out. Thankfull, for one, I kept the receipt and so 5 years later I still received a new starter for the grand price of $0.00. Cool.

[Raven855]

I have bought a staking tool at the local Ace Hardware store before. They are pretty inexpensive. They also have a pretty good supply of the terminals for welding cable and heat shrink too.

[Meotchh]

There are options which do not require special tools to attach the lugs on the cables & they are very reliable.

Those are just a few options.

Special tool? How is a staking tool a "special tool"? Even Bob can operate a hammer and a staking tool. You expect him to figure out what size and which way to turn an Allen wrench? And those fancy connectors will just be lost in the duc tape!

[Meotchh]

If Bob touches tools things will blow up. So any tool is special to Bob!

[MikeFleming]

I didn't get any calls from Bob for Technical Assistance or emergency assistance.

So the project must be complete now? That or the battery was dead.

[Bob Holmes]

One more day. Give me until Monday.

NO! Time is up. Put those pencils down. And turn in your test sheets

^^^ If you had bought Etch-A-Sketch on that day, you would be thanking me just about now. ^^^

Did it start? Inquiring minds want to know!

[Bob Holmes]

Hell no, but i have full battery voltage at the front of the car.

[MikeFleming]

Hell no, but i have full battery voltage at the front of the car. Sounds like Victory! to me!

Try it again once you install the cable to the battery. ;)
