Re: HELP!1990 240DL Starter Cutoff Relay problems ![ALL/1998] posted by Stoney on

I'm installing a starter cutoff relay in my 1990 240DL w/ B230F and when I follow the makers diagram the relay works bt=ut car won't start. The instructions say cut starter solinoid wire Pink #50 and splice the relay between and put second red wire to 12V const. wire at switch. they mean a wire that is +12v in both on and start pos. My volvo book shows this as blue wire #15R . When I put it all together everything is as maker says but the starter will not engage! I called them twice and their books sho w same color wires and terminals so if anyone has idea let me know. I reconnected the pink wire #50 Starter Solinoid signal and car starts normally. Is this the right wire for starter signal? This is a standard kill switch made by Harris0n Automotive Secu rity Systems Model 9828 using a tape microwitch and a relay. Again the relay closes, I hear it click, and their idiot lite goes out but starter doesn't turn over. The only wierd thing is that the OD OFF indicator light comes on when key is turned but not before key turn. HELP ME OBI WAN!!! Stoney

Let's see Ohm's law is I = E/R oh wait is also similar to P = EI so P=Pwr in watts, and I = Current in amps and E = volts so to check if the rating is adequate you would take 30 amp rating times 12 volts = 360 watts so you could power 10 35 watt headla mps with one 30 amp relay! --

Hi I haven't worked on a Volvo solenoid but I have fiddled with my sentra's. Generic relays have 4 connections #30, 85 86 and 87. 30 is for the high amp supply, 87 is the high amp accessory, 85 is ground, and 86 is the microswitch wire(assuming it's a +POS). The ones I get at Chief Auto have a little diagram printed on the side. (better double check the numbers though) All relays operate the same way they must have a high amp supply(the solenoid wire comming from the starter sw), a high amp accessory( the wire going to the solenoid), a ground(unless the low amp switch operates on -neg), and a low amp switched connection. Relays have an amp rating, generic are 30 Amp. Sometimes if the relay gets wet it won't work. You can test the relay you have by dete rmining which numbers there are 30 87 85 and 86 and trying it out on a headlight or a horn when you apply voltage to the right conns. The relay itself is just an electromagnet. When electricity is applied to the electromagne(a magnet that only works when it's charged) When it's charged the magnet pulls a small switch closed and completes the high amp circuit. Hope this helps.

Stoney -
This electrical problem is out of my league, as I'm lucky if I can drive my Sears digital voltmeter around the block - but I have an EE friend (University of Cincinnati) who might be able to help online. Jay Huss. He's also the proud owner of a 1983 24 0 w/200k plus. As President of the SW Ohio VCOA chapter, I'll give him a presidential edict to help you. His E-Mail is: jshuss@ibm.net I assume the Bentley Blue Book is no help in this case, as this is an aftermarket part? What about Steve Seekins? He see ms to be well-educated on any Volvo problem. I think he's already made 7th level Volvo guru status. I'm just happy to be a regional guru.
