  1. still reading 12.5 v from the bat positive post to: block, body and negative post the only damaged wire i have found so far is a black wire from the mount for the ignition cable to the bottom of the distributer. i dont think its the problem but it needs replacing non the less. i might just get a whole new ignition coil all together on account of its age. could i be overlooking something as simple as the ignition switch ? i dought i have tested that properly. thankyou for all the support this far.
  2. its just battery terminal grease. 100 % sure. tests at 12.5 at the end of the pos cable and end of the neg cable all of the fusible links are on the pos side. the are each testing at .7 ohms at the end of the links before it returns to the wiring.
  3. bat is good, posts are clean, terminals are clean. everything is tight. bat tests at 12.64 off, cannot test while the engine is running right now. connections are greased to help with corrosion. testing bat at the end of each cable as well. the negative cable has always been just one wire that connects on the starter. ( on the mounting ear ) it was replaced and put exatly the same way. i would think that would ground it just fine. ignition switch connection is good, perfectly clean and tight. all of the ohm readings for the fusible in the black box by the bat are good. ( im going to double check this tomorrow ) are there other fusibles to look for? i have a wiring diagram but it is usless for me. everything is too small to read for me. im looking for a blow up one right now.
  4. if this is any use the last few weeks it has been drawing way more power then normal if thats ant use i.e. when you use the brake the dash lights would dim by like 40% i would guess. or if you turn the radio up it would click off ( its not some huge system with subs and all that just 2 small speakers in the dash board )
  5. all the battey posts, and cables are brand new as well as the bat it self. what linkes would you suggest starting at. and what is the best way to test them?
  6. so have a strange issue. today firing up the z, ( 1981 280zx ) all hell broke loose. it has been starting a little harder because of the colder weather, but thats normal for it. but then all of the sudden i lost power to everything. no radio / heat/ lights / dash lights/ brakes / signals. nothin at all. the really wierd part is that every once in a while the voltage gauge pulses. between nothing to about 10 (white key at off/lock ) . i havent really touched anything with it i know how touchy electrical can be. currently it is doing this. if you hit the brake. no lights, voltage drops to nothing on the dash guage. pretty much anything you do flat lines the volt gauge. i would guess a main fuse or does this car have one ? if so where is it. a bad relay maybe ? im not sure where to set. any help would be highly respected :)
