Hi Gang,

I was wondering if there is such a scanner tool for diagnosing an 1987 911 carreera. If yes, where can I buy one of those and roughly how much. My understanding is that any OBD1 or 2 scanners are for newer cars only.

thanks for the info. much appreciated.

Not really. 964s are the earliest 911s that work with the Bosch Hammer scan tool. The early L-jet DMEs on the Carrera 3.2s are simple, they don't store fault codes. Apparently there is a special breakout box that Bosch made to make testing all the DME pinouts easier, but my shop doesn't even have that. If you have access to the factory manual and a good meter and electrical knowledge, you should be able to figure out most issues. If not, find a good Porsche shop!

Thanks Chris. Appreciate the info.

Analogue multimeter.

Actually,you will want to use a digital multimeter. An analog meter doesn't have high enough internal resistance, which means that if you are testing a circuit, the analog meter will draw too much current and possibly skew the reading. Also, if you use an analog meter to test a computer circuit, you can possibly damage it by allowing too much by to flow through the circuit. A digital multimeter has much higher impedance, in the millions of ohms. You can get a halfway decent DMM at Sears or similar places, but Flukes are the best if you can swing it.

..............it was meant as a joke. My apologies.

The analogs are the way to go when measuring a variable resistance, as measured on a typical potentiometer,etc....as their's no autoranging "blips" in metering. Otherwise, digital (yeah)....a good Fluke.

Best,

I was just joking about the analogue one because I had to use my dad's ancient one the other day because the cheap digital one died on me. I was more or less just looking for continuity or 12V. Nothing elaborate. That multimeter must be older that I am.

I actually I got the Jooke Matt .. i was going to ask how your 1960's Rusian - Chineze meter was before I read the other posts.

A few of the posts above are correct. I use a Fluke 87 for most measurements. but I also have a 100 Mhz hameg scope for fast rise times and pulse signals. The problem with most meters is the sample rate and if the voltage changes rapidly you won't get a reading. i also have an old analog like mats i use when I just want to see a " deflection" on the meter.
