After my post about the starter problems, I was totally disgusted, so I put that problem on the back burner and began repairing, cleaning and polishing the side trim stainless pieces. That job ate up several heat-shortened days, but I finally got back to the starter issue.
When I first began laying out the new electrical circuits, I consulted several manuals and picked the brains of numerous online automotive electrical websites. Most information for wire gauge and fuse sizes were pretty simple, but I should have further researched start circuit requirements, because I discovered too late that expert opinions varied greatly.
One source I consulted said that a typical old design starter for cars drew from 75 to 100 amps, but that the new high torque starters drew 20 to 40 amps. The wire they suggested for a trunk mounted battery was 2-gauge with a 50-amp circuit breaker mounted near the battery.
Shame on me for not comparing that opinion with a few others when I started. Since then, I found other sites that claim that old style starters could draw as much as 150 to 200 amps, and modern starters from 40 to 75 amps and a 150-200 amp circuit breaker installed close to the battery. They also recommended that I use a 0-gauge cable, and then run the same size ground wire from the battery all the way to the engine block.
So, I'm now thoroughly embarrassed and confused, but decided that for now I will keep the main feed at 2-gauge with the battery ground cable bolted to the frame below the battery. I also replaced the 50-amp circuit breaker with a 150-amp. I might regret not doing more now, but I first want to get the car running to see what else will need modification or upgrade.
Then, to add to the starter problems, the starter wouldn't spin by turning the key to the start position, but it does spin normally when I jumped the start terminal to the main feed. I checked the start terminal, and it receives 12 volts from the ignition switch, but the starter relay does not switch to feed the cable voltage to the starter I ordered a new starter relay today. The one on the car was a new Wells part, the same number as the one I ordered today. I would have rather bought their Standard part, but they were out of stock.
Since the old/new starter appeared to be drawing a heavy load, I decided to replace the starter too. That is rather frustrating since it was a new-build aftermarket part, but now it's well beyond the warranty terms despite the car having never been started. At least I can return it for the $40 core charge. The one I picked up at O'Reilly's. is remanufactured, but it spins like it should.
I can't resolve the starter problem until I receive the new relay, but the starter now spins when jumping the terminals on the relay, so I can now pump some oil around inside the engine.
The stainless trim restoration went pretty well. All the longer pieces are clean, straight and sanded with 1500 grit paper. They will still need polishing and buffing, but I'll wait for cooler weather so I can move that outside where I have more room.
The small pieces that join the bigger parts will need some repairs that I can't do myself. Six of the pieces will need new studs welded in and some expert skill to straighten and polish. I'm taking the parts in to a local restoration shop this morning.
I'm still looking for sheet aluminum with a texture similar to the stock '56 Fury pattern. The Mylar ones I got from James Rawa look nice, but the pattern does not match the OEM aluminum parts. The only aluminum I've found in North America doesn't look quite right and it is clear anodized, so if I wanted it with a gold finish, the existing anodizing would have to be removed and the parts re-anodized.in gold. No local plater was willing to take on that job.
Yesterday I did locate a company in Great Britain that makes aluminum sheets that are similar to the '56 pattern and they also sell it with a mill finish without anodizing. I hope they have a US outlet for their products as I'm sure it would be horrendously expensive to ship a large sheet to Texas so I can cut out the parts and then ship them to wherever they can gold anodize them.
I can now sympathize with you Forward Look restorers around the world who are faced with similar shipping problems with your American classic cars!
Hey Gary, I have been thinking about your (starter) wiring. Mostly out of complete self interest and being a cheapskate. I also trunk mounted the battery (actually in the spare tire well on a wagon) and ran long runs of what it think is 4 gauge to the 318 stock starter. I have only started the engine and not driven the car but I think because of the fuel injection it starts quickly with no battery problem. It seems to work well, I hope so because I have just ordered the same size for my next project.
ReplyDeleteIt is frustrating to find so much conflicting information when researching electrical circuits. I'm like a lot of guys who know just enough about electrical design to be dangerous. You are probably right about your FI working so well that it doesn't cause a heavy load on the circuitry. In my case, I was cranking the engine several seconds to pump oil, so the 50 amp CB tripped. With the 150 amp breaker, the 2 ga wire felt warm, but it never got hot enough to be a concern. Now that I have good parts and the starter seems to be working okay, I'm getting anxious for the day when everything else is ready to go and I can put gas in the tank! BTW, you said you are working on your "next project". Is it as radical as the Dakota wagon?
ReplyDeleteYes and No. It is a "other make" panel truck that will be my last project ever, just a basic street rod without frills. I bought a fox body ford for the FI 5.0l HO (302) engine and I noticed that the front suspension cross-member is a strut hybrid in that it has shock towers but lower control arms with coil springs. I going to see if I can use it. This originally was a terrible handling car but I am to the point of only going for ice cream anyway. .
DeleteDang it Ray, you really are a glutton for punishment! I like a challenge, but I'll never live long enough to take on another one if and when I finish my '56. I'd suspect Ford fans have a dozen aftermarket or doner car suspension setups available for about any year panel truck, but from what they tell me, the Fox body is not a favorite body or parts donor. I think I'll stock up on a lot of popcorn when you start in on that project!
