Question about 1993 Volvo 850
Original coil is kapoot it does not work have put on a replacement but not sure of originals resistances
Posted by Anonymous on
Specifications per VADIS 1993 Volvo 850 2.4 Non Turbo:
Ignition Coil, power stage:
Resistance between terminals 1 and 15 (primary winding):0.5-1.5 Ohm
Resistance between terminals15 and HT terminal (secondary winding): 8-9 kOhm

These models had problems with the blower motor power stage, which is what controls the fan speed, and the blower motors wear out. There a good chance it needs both!

The most common cause is either a bad air pump (under your battery tray) and/or a bad SAS check valve which is connected in to your exhaust next to the firewall in the engine compartment. It could also be a bad relay for the motor. Less common, but possible, other bad components are the vacuum solenoid that controls the SAS valve, which is located by the radiator or a broken/leaking vacuum line to or from the solenoid.
You can test the motor by jumping the relay or applying 12v straight to it. If the motor runs it most likely is not the problem. If not, it's likely that there is water in it and you should replace both the motor and SAS valve. The SAS valve is a pain to get unbolted, at least on turbo cars. You can check the solenoid by just making sure there is vacuum going to the SAS valve a few seconds after starting up the car cold, and checking the lines for any obvious wear in the rubber elbows or breaks in the plastic line.

SOURCE: VOLVO 850 RADIO/CD REPLACEMENT
Yes, its simply to remove the radio wich is there (two clamps, one on each side) retract the connectors.
You might need to buy a compartment to conceal the part of the opening that will be exposed when removing the bigfront-radio.
(Volvo-dealers can help you) And a cableset wich contains the connectors to the Radio-connectors in the 850 and directly to the radio you buy. (Most radio-dealers hava all kinds)
New radio mounts in only e few hours. All included.
Theese Volvos are very well prepeared for this.

Two questions: Is your odometer working? If not then it's probably a broken gear by the stepper motor that Emissionwiz mentioned. Is your ABS and/or TRACS light on intermittently or constantly. If so that is a common sign your ABS control module has gone or is going bad. This usually happens before the speedometer starts acting up. Either one of these will start intermittently and finally end up with the speedometer not functioning at all, and both are pretty common failures with this model.

If you suspect a malfunctioning ignition coil, check the resistance of primary and secondary windings. Do this when the coil is hot, and again when it is cold. Also measure from the case to each connector. The primary windings should have a very low resistance, typically from a few tenths of an ohm to a few ohms. The secondary windings have a higher resistance, typically in the 10,000 to 13,000 ohm range. To get the actual figures for a specific coil, check the manufacturer's specs. But as a rule of thumb, primary windings range from a few tenths of an ohm to a few ohms, and secondary winding may be 10 ohms or more.
