Does anyone have the dimensions and a photo(s) of the original battery (manufactured by Yuasa) that was installed in the Series 1 cars? The dealer says that the current part number for the Group 24C battery is 999M1-NB24C. I want to verify that the dimensions, terminal post positions, and appearance are close to original. Thanks, Keith

Does anyone know how do i need to route the wires that go to the rear speaker panel sold by MSA in the trunk of the car? I will be installing the transmission tunnel vinyl trim and would not like to miss the correct routing of the rear speaker panel. I only found this diagram on the web but it tells me nothing. i think the routing of the front speaker is really straight forward.

Ever since I purchased my '71 240z the power antenna has not worked. I pulled the hatch panel out to reveal the original single speaker a Harada model 6424 power antenna. It does not have the bullet tip at the end of the mast but instead has a squarish cylinder. I tried putting 12v to the wires each way and got nothing. I had to open it up in order to manually wind the rest of the mast down so I could remove it from the car. With it on the bench I could see how much rust it had that might have lead to its demise. Before giving up on it I would like to dis-assemble it and possibly rebuild it. I was hoping to find a guide that ilustrated this as it seems very easy th…

I've got a short somewhere... Ok actually found a few but not the actual problem... New motor is in with new matchbox dizzy and alternator. Old ignition box unplugged and alty wiring has been double and triple checked (and more). Car runs great and I'm excited to go places but I have a lighting issue that is keeping me off the road for obvious safety reasons. I first noticed it on my first early morning drive when I could not see the cluster. No dash lights and no running lights. I checked all the fuses and they are fine. So checked everything the car has: Headlights, brights blower fan, brake lights, Hazards, Turn signals all work. Wipers do not. I've read about a…

Need some help and direction. Headlights flicker sometimes over bumps. Found that if I tap on my relays with the lights on the lights flicker and the relays chatter. This is a 71 which I upgraded to relays . Oddly I have my fuel pump on a relay also and I can get it to chatter also by tapping it. Only thing I think they share in common is the power source. The main power comes from a power strip that I have connected directly to the back of the alternator . Pretty sure the grounds are different between the headlights and fuel pump. Appreciate any testing methods

Does anyone know where the part numbers/boiler plate type ID is located on a stock coil and starter for 1970 240z? I can only see Hitachi stamp cast into some starters. Thanks

I need a new door jamb switch for the passenger door on my '78, because the pin is pushed in get in and I can't get it out. I think I can get one from the APS, but the website has several with two wires, but different terminals. All I need to know is what kind of terminals are on the wires; two bullet, or two blade terminals? BTW- Does NAPA have them? thxZ

This is on my 76 2+2. The other day my daughter was following me home and when we arrived she said my right (passenger) side brake light wasn't very bright. I don't know how long it's been like that, may be ever since I bought the car a couple of years ago and then some. Anyway, when I put the brakes on, the parking element on the right side lights, not the brake element. When I turn the parking lights on, the correct parking element lights, but then if I also put the brakes on, neither element lights. I tried switching bulbs, but it doesn't change anything. The left side (driver side) lamps seem to work fine. Any ideas where in the wiring harness I should sta…

I need some help with my internally regulated alternator. I have a 1976 280z that I have been restoring (full rotisserie resto-mod). The car is pretty complete mechanically. I have removed the fuel injection and fuel injector harness and control. I have removed the distributor and transistor ignition module. In their place I have triple OER Carbs and an XDI electronic ignition. I don't that either mod bears on my present problem. I have installed a 60a internally regulated alternator. I performed the wiring modifications shown here: http://atlanticz.ca/zclub/techtips/alternatorswap/index.html The problem is that it doesn't seem to work. I can …

During my recent time at the recent ZCON 2016 event in Toronto, (best ever by the way, said the un-biased Canadian) I made several interesting observations about the 240z's that were present. Most observations were something like "I have to step up my game if I ever want to win anything at these things if I bring mine again". Some mighty nice machinery indeed. As the OCD perfectionist in me is never quiet, I could not help be notice something interesting about almost ALL of the 240's present. It began with the judged show on Wednesday. I was staring longingly at everyone's engine bays, as I'm in the midst of doing a relatively stock-ish 71 resto and wanted a bit of g…

Just did a Pertronix ignition swap on a 72 automatic trans. It had the dual points dizzy but I swapped out with a single point before doing ignition swap. Engine runs fantastic, but I've lost the tach somewhere in this . The auto has additional wires that might be part of my issue. I did away with the ballast and tied those wires together . They seem to have no bearing on whether the engine runs or the tach works- which kind of confused me. The autos also had this relay set up for the secondary points, not sure if they are tied in somehow to the tach . Any insight would be appreciated

maybe this is your problem. the ground wire is just folded over the plastic, and the socket is pressed in. you can see the corrosion on the socket and the copper wire. corrosion doesnt make for good connections here is my solution, pull the socket out of the plastic housing and solder the ground wire to the socket. no problems now
