You sure that the top wire goes into the engine? May have originally connected to the fluid level sensors in the MC tanks.

Power issue after fuse box upgrade

Please let us know what MSA says. -
Power issue after fuse box upgrade
Miles replied to ~KnuckleDuster~'s topic in Ignition and Electrical
Work logically. The first question I ask people with a sudden electrical problem is: what was the last thing you did just before the electrical problem occurred? For example, a guy with a 240z kept blowing a fuse for the side marker and dash lights every time he turned the lights on. He just kept replacing the fuse each time this happened. So I asked him: "what was the last thing you did to the car before it started blowing fuses?" He replied "I removed the right rear marker light and replaced it" Turned out he mixed up the ground and power wires so each time he turned on the lights there was a dead short in the lighting circuit. -
Power issue after fuse box upgrade
Miles replied to ~KnuckleDuster~'s topic in Ignition and Electrical
What car 240z, 280z etc? Any wiring modifications? Re-install the original fuse box to see if it behaves the same way which will eliminate the new fuse box as the problem. You could pull one fuse at a time to isolate the problem to a specific circuit and then go from there. A call to MSA may help. Kinda depends on which MSA tech you get. -
1972 240Z Brake upgrades.

When I was considering rewiring one of my 240Z cars, I researched EZ wiring. There are a bunch of tutorials on HybridZ and other Z sites. I recall one member made a pdf wiring list that showed the brake wire connections. The brake lights are actually controlled through the T/S switch. For example, when making a right turn the T/S switch disables the right brake light etc. Some HybridZ links: https://forums.hybridz.org/search/?&q="ez wiring"&type=forums_topic&search_and_or=or&search_in=titles&sortby=relevancy

Oil Pressure Gage Not Reading Correctly With SBC

Looks like you have the correct sensor. The sensor could be defective. -
Oil Pressure Gage Not Reading Correctly With SBC
Miles replied to Twisted46's topic in Gen I & II Chevy V8 Tech Board
Sounds like you have altered the stock wiring. So the following may or may not help you, but may serve as a process of elimination as you trace your electrical problem. Possibilities: Wrong oil pressure sensor? A wiring alteration is energizing the oil pressure sensor circuit when the ignition switch is in the start position and then de-energizes when the switch is released to run mode. Check the ignition, fuel pump and starting circuit wires. Check the circuits that have been altered to see if they have been cross connected to the oil pressure sensor. Test: connect a volt meter to the yellow and black oil pressure sensor wire. Note what the volt meter does as you turn the ignition switch slowly to each position on the switch. This will narrow down which wires to inspect. Look at/test these wires at each position on the ignition switch : Yellow-black - oil pressure sending unit Black-white (without protective sleeve) - tach terminal on HEI distributor Black-white (with protective sleeve) - battery terminal on HEI distributor Black-yellow - S terminal on starter Black-blue - energizes the fuel pump while cranking (260z and 280Z only). Note: 240z uses a green-white wire to run the fuel pump while cranking (energized just before start position on ignition switch. This is just a starting point. You have some detective work ahead of you. -

Check your wiring to the oil pressure switch, oil pressure safety switch etc. If you followed JTR then your pressure switch and oil pressure safety switch should look like the attached picture. Post the wire list you used for the oil pressure switch etc and where each wire is connected. -

Read the brake FAQs and search the brake forum. Also search the internet by typing "240z brake upgrades". Note: stock brakes are fine -

Anyone have a workaround for the Switching Module?

I was going to suggest you contact Randy, but I no longer have his contact info. He used to advertise on Sacramento Craigslist. -

The part number you gave is for a relay inhibitor switch. You sure it is part of the light circuit? https://www.nissanpartsdeal.com/parts/nissan-relay-inhib-sw~b5230-89985.html The right half of your schematic is missing. Here is the complete schematic which shows the combination switch (lights, wiper, washer and turn signal). The combination switch is located on the steering column: -

Contacts in the TS switch need to be cleaned and/or adjusted . Common problem for all Z cars. You can repair the TS switch. Search for turn signal repair. Start here: https://fiddlingwithzcars.wordpress.com/2012/12/04/turn-signal-repair/ -
No (Low) Rear Brake Pressure
Miles replied to Twisted46's topic in Brakes, Wheels, Suspension and Chassis
You measure from the face of the aluminum spacer on the booster to the tip of the push rod. So, if you replaced the stock 7/8 MC with a 15/16 MC, which has a deeper socket, you adjust the push rod out 0.53"as measured from from the face of the aluminum spacer. The 0.53" is a starting point. You may have to fine tune the push rod length by making small changes and then road test the car to make sure the rod is as close as possible to the bottom of the MC socket without pushing the piston too far inward which will cause the brakes to drag or lockup. If the push rod is adjusted too long, the piston will block the return port in the MC and the brakes lock up after 2 or 3 stops. If this happens, open the MC bleeders to relieve the built up fluid pressure, limp home, and adjust the push rod a little shorter etc etc. If the pedal moves too much before engaging the MC you will need to lengthen the push rod in small increments. Note that you do not have to remove the MC to perform this adjustment. Just remove the mounting nuts and then pull the MC out and push it aside. There is also a tool to measure push rod length.
