further found in TSB
attached is part of TSB 07.3 001 dated 01-01-85. I know it [the number of the TSB] appears it is part of manual but it was not in my manual. I found this on AllDATA data base under the Technical Service Bulletin list.
this is part of the TSB :
5. Connect the additional wiring harness to the 16~C temperature switch and the main wiring harness (Figure 5). Attach the ground wire to ground (W2 - at the head lamp assembly). Secure the additional wiring harness by tying to the main harness.
19 Temperature switch 16~C (Engine oil) 100 Acceleration
enrichment switch
a To main wiring harness
W2 Ground, right front(at headlamp assembly)
W5 Engine ground
In a quick look at my 500 I believe there are some incorrect vacuum connections also but I have not had time to get into it. I have both a red thermovalve and a white thermovalve- does anyone know which is the 50 degree C and which is the 70?
Appears the valve is controlled by vacuum from the warm up compensator- the vacuum port on the backside of the regualtor. mine was plugged into the top of the WU regulator. Is that just supposed to be plugged- the top -sometimes referred to as the vent?
Thanks. I'll report on results after I "re-arrange" the vacuum lines - maybe not a bad accel enrich switch after all just hooked up incorrectly.
Chuck, let me know if you want any more of the TSB and I'll email it to you.
