Hey guys, first piece that is finally going back the other way, the blower motor/heater core housing. I know they are small parts but must be done. Feels good to have something recontructed instead of deconstructed!! One question, there are 3 grommets that that go between the blower motor mounting plate and the fan housing. I haven't seen any replacements. I could use these but they aren't in great shape. Any ideas. Thanks in advance!

My fuse box melts, some times smokes when any lights are on (including the fact that all the lights are dim and driving at night is hard to see). Ignition and charging problems come and go. After replacing relays doing reshearch and tryng to understand the maze of wires and diagrams that dont make sence. (I guess that is why I'm a plumber and an electrition is an electriton.) However I do have 4 years race mechanic/restoration experince including wiring a race car (noting vitage race cars dont requier very many wires). I did find a hot rod harnes kit at Centech for a good price. I'm looking for any advice or any one that has done this whether it was race car or not. By th…

My '73's electrical system is doing some unusual things that make me wonder what it's going to be like after I upgrade/replace things like the alternator (105 amp), headlight wiring (better), new MSA fusebox etc. When driving down the road with nothing on I periodically hear clicking in the passenger footwell making me wonder what's trying to operate. The wipers move, but only a little bit then seem to run out of "steam". The headlights will come on only when the switch is cycled 2-3 times. Is the clicking a result of the dealer installed A/C trying to cycle? (I thought I had it switched off) Any recommendations would be appreciated, I'd like to get things more reliab…

Hi all, Using the search function I came across several questions regarding Z Specialties 105 Amp Alternator. I just purchased one and thought I share my experience with it. Since I've owned my '72 240Z, she has always had "slow" turn signals. I've replaced the flasher unit, the switch on the steering column, cleaned connnectors, and probably a whole lot more over the several years I've owned her. Some of this actions made marginal differences but, the end results were not completely satisfying. Two months ago I had A/C installed in my 240Z using the kit from MSA. Works great btw here in the central valley of California. The resulting drain on the electrical system …

Does anyone of our members know how to decode the date codes that are printed on the back of the guages? My series 1 has a estimated build date of Dec 70 and my guess is that the date code is 5th Dec 1970. Can anyone confirm this?

This is a weird thing that happens intermittedly, and I'm wondering if someone can shed some light on this. Usually when the car is running, the volometer will settle in to a reading between 13 and 14, but now and then, it'll erratically jump down to around 12.5 or so in consistent intervals. This is especially noticeable at night when my headlights are turned on because they will dim each time the volts spike down. It only seems to happen when the car is idling which is leading me to suspect the alternator, but I'm curious if this could also be a connection thing too. Your experience is appreciated. :nervous:

Some advice please! 1. My headlights only work on high beam. I have pulled and checked/rebuilt the switch. Pulled the headlight (replaced them too). Pulled all the connections I could find and cleaned them. Checked all the fuses. Checked everything with a meter...there is juice and continuity everywhere. I am stumped!!!!! 2. I notice the car has been hard to start. Pulled the Cold Start Injector and jumped it strat from the battery...works. With the electical connection plugged in does not work. Checked the plug and it is not getting juice. Help! Am I missing a relay or link or something somewhere? I could not get to everything without disassembling the harness…

This car's going to drive me mad. In addition to the other wacky problems I'm having the timing just can't be adjusted lower than 10 degrees, at this setting it runs like hell and pops quite a bit (SUPER RETARD!). Ahem. Anyway, I have this odd feeling that this isn't caused by the oil pupm/dizzy shaft being out of whack, but instead maybe the chain has jumped a link (I STILLL really dread removing the front cover, due to my garage being a parking lot at the moment) and the damper mark has shifted as a Result or Consequence of this little occurence (damned infuriating, really). The chain itself is rather loose on the right hand side of the engine and tight (due to the tens…

I experienced the infamous bouncing tach issue this weekend. It occured when I was stopped at idle, with the tach needle bouncing all over the place. When in gear and driving it was minimal. I then noticed a "whirring " noise from under the hood near front of the engine. It appeared the noise occured exactly the same time as the tach bounce.I suspected it was from the dizzy, but im not sure. I pulled the cap and rotor off, didnt seee anything obviously amiss though. Note I DO Not have pertronix, just stock ignition system. Any ideas? I note some foks said they were able to get their tachs fixed for about 50 bucks. Wonder who works on such items?
