The B&B tester simulates the pulses generated by the "star" gear to see if there is an equivalent output pulse to generate the spark with the coil. It does it at two speeds to make sure the unit works at low rpm and also at high rpm. The tester is not unique to our modules; it's a universal tester to check many brands of ignition modules.

No need to punch out the roll pin. With the distributor in the car (or held in place in a vise), use two screwdrivers to carefully pry the 4 point "star" unit. Do not nick the edges of it while doing this. Once that part is off the shaft, the module comes out easily with a small phillips screwdriver. Don't lose any of the spacers or hardware.

You don't need the whole distributor; just the ignition module will do and you should add a known good one to your glove box. The comments on distributor shaft wobble and faulty wiring that someone else mentioned are plainly visible if you check the innards of your distributor and should be resolved sooner rather than later especially if you're planning a long trip. If you want a quick lesson on module removal/replacement, arrange to meet me at PAP some time when there is a known Hitachi distributor available and I'll show you the easy way to replace the module.

Testing outside the car: Make friends with the counter people at B&B Parts in Redmond. They have an electronic tester that will test your module for you at low speed and high speed. Try and let them allow you to do it since the clamp to ground the module is critical. If it's not properly connected the module will fail the test. Remember, their purpose is to sell you a new module. Failure mode: The Hitachi module almost never fails suddenly. It usually starts to give you intermittant no starts or failures before it finally dies. If it dies on you suddenly you're either very unlucky or not paying attention to the warning signs. Rumor: I was told that the Schuck's version of this module had a tendency to fail after you jump started another car with jumper cables. I don't know if that's true or not, but my first module failure was about a week after starting a friend's car with jumper cables. Installation tip: The underside of the module is probably a heatsink for the components. I always install mine with the white goop for better heat transfer (get a small tube of it from Radio shack). I don't know if that helps but I normally get many years out any module I've installed (and all of mine were pulled from cars at PAP and then tested at B&B so they are not "new"). Purchase tip: The first one I bought at B&B, I was offered a price of $85, $125 and $200. I asked what's the difference? 90 day warranty, 1 year warranty, or lifetime warranty was the reply. I bought the $85 one and it lasted more than 5 years. Generally speaking when it comes to electronic components like this, if they were properly designed and manufactured they should last a long time. If not properly manufactured, they will usually fail within a week so the 90 day warranty is really all you need. Smart tip: Get one from a wreck at PAP and have it tested and keep it in your glove box for emergency repairs. Minimal tools are usually all you need to fix it on the road. And it's pretty easy to test: no spark, it's usually the module. If not, you've eliminated the cheapest part (if you get it from PAP). All of these comments refer to the Hitachi ignition module. I have no idea if the ND version is prone to the same issues. I decided a long time ago to only "stock" parts for the Hitachi distributor because I thought it was easier to work with.

The News Just Keeps Getting Worse

You never said whether Bucky was FWD or 4WD. Which? -
Removing the bezel is scary since you don't know whether you're actually removing it properly or if you're about to break it. Also all the screws holding the bezel, control panel, and such together are on the inside and really hard to get at without disconnecting all three cables and electical connections. Trying to replace the two bulbs without doing all that is a bit tricky. I have that junkyard control panel here and still don't know how to get at the bulb for the A/C control.

I bought a climate control panel from the local Subaru only yard so that I would be able to see what I was in for. I wound up prying the bezel from the top VERY CAREFULLY to get it off the dash. After removing the left dash kick panel and with the vent control fully counter-clockwise I was able to remove the vent cable from its peg and free the cable sheath from the clamp on the left side of the dash. This allowed me some more access to the rear of the climate control panel. Here's a pic from the unit I bought at Aaron's: It's shown with both dials fully CCW (as seen from the front). Notice that the lamp holders are impossible to remove or replace unless you have super small fingers. Here's a picture of the rear with the dials fully CW (as seen from the front) so that now the lamp holders can be twisted out, the lamps replaced, and the holder twisted back in. Still not easy but do-able. The lower lamp holder shown above is for the vent status dial. This one is the easier of the two to replace. The temp dial lamp at the top is more difficult. I couldn't figure out how to replace the A/C indicator lamp which is inside the A/C switch. I didn't think it was important to have it working once the other two lamps were okay. After I put everything back together, I was pleasantly surprised to find the A/C indicator was working. Here's a pic of the old bulb I removed: If you want to see more detailed pics, check out my Repair album at http://www.ultimatesubaru.org/photos/showgallery.php?cat=959.

I'm going to have to cancel my order for bulbs at the dealer; I didn't want to leave my wife's car sitting while I waited for the back-ordered bulbs to come in and I had partially removed the panel since I had bought a replacement control panel from Aaron's Autowrecking for bulbs (which were missing! ). But the spare panel made it much easier to see what I was dealing with. I tried NAPA on the off chance that they would have bulbs. They did! Only difference is they don't have the green mini-condum around them but I don't really care. They work and cost $1.99 plus tax for two! Part number is from Wagner #17037. I'll post up some pics later tonight if I have a chance.

OK; glad it's covered. Regards and Happy New Year!

I'll get you a better one; you just need to butt splice it in or solder and insulate. I'm going to PAP tomorrow so I should be able to find one for you.
