HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

Help Locate/I.D. a couple wires

Post  xschop on Mon Sep 14, 2009 3:58 am

The ink on some of the masking tape I used completely faded when I was disassembling everything a few months ago.....so where do these wires go? The large one is a thick 8-10 guage solid black and loops around in the pic. The red one has thin black stripes and the blue wire both connect near the firewall....Any Idea? drunken

The ones on the right with the rubber grommet go to the alternator. The fat one is the b+ wire which should go to the battery to charge it, and the other is the excitation wire that turns the alt. on with juice from the ignition switch. The other I'm pretty sure is the starter solenoid ( ign. in start) If you check the fat wire ends with a ohm meter I'll bet its the same wire. It's the b+ that goes to the battery to charge it, from the alt.

So the Large guage Black wire connects at the alternator along with the Blue wire. But the large black wire then goes to the battery POS (+) .....If this is so then the Red/Black stripe wire needs to go to or near the battery as well not down by the starter?

the smaller red wire should go hot when you go to "start "on the ignition switch. That red wire goes to the small post on the starter solenoid. You can hook both wires to the starter( the fat to the big lug, the small to the small lug ) but you still need to bring your fat battery wire down from the battery to the fat lug on the starter also. I ran my b+ (fat wire from alt) wire to my battery so I only have 1 fat wire on my big lug at the starter.

If you notice those wires are together because thats the way Porsche ran them. They used the big lug on the starter as the connection back to the battery since the wire from the battery also mounted on the same lug. The blue wire and fat wire went to alt.

So friggin Porsche has hot (+) wires in Black to confuse the Americans putting in their V8's.....
Thanks Dallas.
So to make things simpler, I will copy what you did. Run the large black wire directly to battery from alternator, and there is already a larger gauge wire that will run from the battery to the large starter bolt.....gotcha and thanks for the knowledge.

Yeah, why porsche used a black wire for the b+ I'll never know. I changed it to red after I pulled the gto harness apart. That b+ wire comes from the stud on the back of the alt. I have another plug with 2 wires on the alt also. 1 wire is excitation, the other ran up to the battery terminal also. I was a thin guage wire that changed colors right at the batt. It also changed guage. It turned out to be a fuseable link to protect the alt. It was very thin guage. Check the alt wiring diagram for the alt. you use to be sure you pick the proper terminal for excitation.
