31 Standard 8 - startup - light circuits
#91
Home away from home
Home away from home

Greenfield
Light circuits: I decided to start circuit testing. Car was rewired with a Harnesses Unlimited loom 30 years ago, which is in perfectly fine shape. I didn't want to find out I had an electrical problem after hooking up 700 cold cranking amps to the system, so I hooked a 6v lantern battery to the battery contacts and use a multimeter on the various circuits to detect for voltage. It's simple: when circuit is closed volts are good, when circuit is open, no volts are good.

None of the lights are hooked up, I just have loose wires at this stage. I got good volts for the regular and high beam light circuits. However, when the light switch is completely off (lowest setting) I'm getting a smallish amount of volts for the "parking" light circuit. What exactly is this circuit -- would it be for fog/auxillary lights? There is a separate circuit for the fender lights which I have not yet tested. Is the "parking" light circuit contained in the headlight assembly?

Obviously though, detection of volts in the circuit when the switch is in the off position is troubling, and I take it something is touching either in the steering wheel lever or in the switch box at the base of the steering box. Any advice on where to focus my efforts?

31 Standard 8 - Startup - Ignition
#92

I'm soldiering on towards the starting the 826. Some more quandaries:

After getting the distributor situated, I went to look at the coil/ignition system. Oops, the key didn't work. Won't turn a bit. So, I pulled the coil assembly out to get an education in early 30's theft deterrent devices. I pulled the coil out, took the key mechanism off, and noted the brass cams that rotate on the base of the coil that apparently activate the coil. I decided to soak the key mechanism in PB Blaster in the hopes that the tumblers in the lock cylinders need to be loosened after not being touched for 34 years. Maybe there is corrosion between the lock cylinder and pot metal housing. A guy can hope after all....

Shockingly, ignition parts for a 90 year old car aren't readily available at Pep Boys. I'm thinking of one of three solutions: 1. fashion a copper disk to fit at the base of the coil, sandwiched between the contacts on the coil and the brass cams to essentially override the key, but use the existing Northeast coil 2. Independently mount another 6v coil, effectively rendering the entire NE part ineffective 3. buying a Atwater Kent replacement. Any suggestions, or anyone with a part you'd be will to sell?

Many thanks to all; Last weekend I pulled the distributor, converted to a single point conversion system, lubed/greased everything, cleaned all the rotor and distributor contacts, got the rotor snug, checked the advance mechanism, set point gap, then got the timing down just right at least according to the factory manual. While at it, I cleaned all the old dry grease off the starter bendix and re-greased. Saw the solder failed on one of the joints of the oil filter return line, so I pulled off and re-soldered.

31 Standard 8 Distributor
#95
Home away from home

Howdy Folks - I"m getting ready to start a 31 Standard 8 for the first time in 30 years, and I'd like to pull the distributor out to do a single points conversion. I wanted to find out if there is any special guidance before doing so. I've got cylinder 1 at TDC, and I've got the rotor pointed to the number 1 plug wire. To remove, do I just need to remove/loosen the distributor clamp? Also, I notice the rotor sits on the shaft and is noticeably loose. This perplexes me, as it seems the rotor would jump all over the place during operation. Should it be like that, or should it be on there tight? Anyone know if Northeast made two different size rotors and I happen to have the larger size? I don't know the model number of the distributor as the tag was replaced. Lastly what is the large chrome adjustment knob do - is that for micro timing adjustments?

I can't tell you how happy I am that this is freed up, and I don't have to pull the whole thing apart.

Success! After filling the engine with 2 gallons of a 50/50 mixture of diesel and ATF and waiting two weeks, the engine rotates without any problems. Whew! Now I just need to pull the manifolds to remove the excess mixture, but that is an easy job.

I would first suspect distributor timing and the condition of the points? Then perhaps check out the mixture screw on the carburetor to see if it is too lean?

Thanks for the suggestion. I backed off the engine a quarter of a turn, then I filled the cylinders with a 50/50 mix of diesel and ATF. Then, I removed the carb and valve cover and endeavored to clean the valve area as best I could. I'm glad I did because I found a piece of wire from a wire wheel in there. I then soaked the where the valves pass up into the block and guides hoping I can get penetrant from underneath. While I had the access to the valves, I took note of which valves were open and closed and recorded it down. I let it go two weeks then report back.

Hey Ross - Thanks for sharing the success story on the atf/acetone mix. I've considered doing that but am concerned that any spillage on the engine might ruin the paint on the engine, which has been done very nicely. I've been considering a thorough soaking of diesel/atf instead as some people seem to have luck with that.
