CDI+ with megasquirt
Jonny Retrofit replied to SteveK's topic in Upgraded CDI Ignition technical forum
Basically, I am 'dialing in' the advance so that what is on screen matches the actual timing shown on the strobe lamp. -
1990 964 Compressor Won't Start
Jonny Retrofit replied to Lennie Diyco's topic in Electric Air Conditioning technical forum
Hi Lennie, We reviewed the DIAG logs you sent in. They show that the engine is not started ( 'WaitForStart'). The engine must be running for the A/C system to run. We also note that your battery voltage is extremely low - less than 8V.

Start of season maintenance

Most likely ok. Believe it or not, scroll compressors are not inherently balanced so can be a little 'wobbly' until they get up to speed. Sounds ok to me. -
87 911 Carrera 3.2 headlamp circuit (100w bulbs)
Jonny Retrofit replied to Moose's topic in Blade Fuse Panel technical forum
Check the bulb wattage rating. If you are blowing a 7.5A fuse then either each of your bulbs is greater than 100W (7.5A x 13V = 97.5 Watts) or there is another issue ( like bad contacts/wiring in the bulb connector). If they are 100W bulbs then you might need to go to 15A fuses since the 7.5 would be marginal as calculated above. 15A should be ok since the standard Porsche headlamp wiring is 1.5mm2 wire which is good for 20A so the fuse will blow before the wire melts! The H terminal can be used to provide another ‘way in’ to the fuse panel from the battery so the current is not all carried down the single factory thick red wire (which is good for about 40A). Fit a 2.0mm2 or similar red wire between H and the battery + if you really do run 100W bulbs to spread the load. -
1983 911SC Rear Panel Fuse Block Install
Jonny Retrofit replied to TYARBS's topic in Blade Fuse Panel technical forum
Thanks for the comments. Correct, the white lines indicate an internal bridge on our panel effectively replicating the copper bridge. Wire not needed on SC. -
Sorry for late reply. A bit of illness, Easter break and moving premises left this thread wanting! Here is the cable drawing for the switch loom. CLAS01-DWG015-REV01.pdf The ECU needs 12V on the black/white wire to switch AC on. 12v is provided on the red wire. If the ECU button mode is set to Momentary, then a pulse is expected. If the ECU button mode is set to Latch then a high level is expected. You can change this in ECU by typing BUT=0 or BUT=1. Use LIST to verify changes. The Brown/Yellow wire is the LED lamp wire. It is a 12V PWM drive to control the dimming. Do not use a conventional bulb. The black wire provides the ground for the LED.

rear fuse panel 1988 911 3.2L
Jonny Retrofit replied to PhilipJ from Boston's topic in Blade Fuse Panel technical forum
On your Carrera original block, all 3 fuses are linked by a brass strip on the back. On our fuse panel, only two of the fuses are linked as indicated by the white stripes on the front side. You need to link the bottom two fuses ( in your picture you have linked the top two) so move the link down. -
Best way to lock a points distributor
Jonny Retrofit replied to E1974's topic in Upgraded CDI Ignition technical forum
That sounds like a typical early fuel injection issue. I would research how to setup / check the CIS.
