  1. My son's barn find 86 Brat. Has multiple issues we've been working through. Currently were working on the charging system. The alternator is charging at 14v at idle but the charge warning light burn dim. EGR, brake, charge, and stop lamp. These light go out at near 2k RPM. I'm pulling the alternator out now to check the brushes. Any ideas fellas?
  2. EDIT: 7/30/15 Brat starts and runs, sorta! Still need help making sure where the wires go on the ignition switch. Currently we have it plugged in as IG(nition)->Black A(ccessories)->Blue R(egulator/rectifier)->White(this goes to battery) S(tarter)->Black/Yellow(this goes to starter) With this set up we can get the car to run but not idle. It will run as long as we keep the key turned. What we are unsure of, is there supposed to be a line that comes from the regulator/rectifier? There is another spade on the switch "B". How is the ICU supposed to be hooked up in the engine bay? There are two spades on it but we only have one wire plugged to it. We have a weak orange spark from the coil to the disty but when i try it from the plugs to the frame i get purple. On 1 and 4 we are getting intermittent spark to no spark at all. ------------------------------------------------------------------------------------------------------------------------------------------------------ Hello there! I just picked up a brat that needs a little work. Supposedly it ran last year so I'm hoping it won't take much to get it going. Its a 1981 1.8 AWD. He said it needed a new coil so I got one and put it in. When I put the battery in the blinkers were going off and when I went to turn the flashers off the horn went off and there were some sparks coming from the steering wheel. There are also a lot of things missing and wiring ghouls unknown to be. Here are some pictures of the my wiring woes. I have a Haynes manual but I can't really decipher it. I have yet to find a colored wire diagram, which I think would be more helpful. This large blue wire is grounded to the frame and has a male connector. I have no idea where it goes. The mostly black wire is spliced into another black wire that goes into the blue connector. Any ideas of where it goes and what it does? I'm not sure if both of these are female connections, I know one of them is for sure but the other may just be packed with dirt. They lead back into the firewall. I also have no idea what they connect to. The only idea I have about the blue female connection is that it may plug into this unit that is mounted on the strut tower because there is a male lead but that entire unit is grounded to the frame. Also, what are these boxes? [/url] Here is the beautiful fuse orifice. Is the circled one a fusible link? (PO said that the car wasn't getting spark and guessed it was either the coil, fusible link, or regulator). The green fuse is melted but not blown. Does anyone have a list of what the fuses are for?
  3. My 1993 California Loyale passed smog for every test except it was 3pts high on the low-speed hc test. I have an SPFI, 5speed, with 180k miles on the car. I noticed the fuel pressure regulator vacuum line has zero vacuum at idle and when I rev the engine! I blew some air into the passage and it only exits from a port ABOVE the throttle plate! According to theory, it's supposed to get manifold vacuum below the throttle plate so it can actuate at idle to reduce fuel. So why is it ported to above the throttle plate at atmospheric? What's funny is I don't have any idling or other problems associated with a faulty fuel regulator, yet it appears it's not doing anything. The shop manual shows the SPFI engine has the port above the throttle plate too. However, it's below the throttle plate for the MPFI engine! Anybody have an explanation for such a strange setup? Is the regulator in the SPFI just a 'fuelish' invention in this case?
