Ignition Relay

[74spider]

Could someone please send me the instructions on how to install a relay to my ignition to help stop the old "click, no crank" problem.

I have seen it here before, but I can't seem to find it with the search.

I think RT might have it.

Thanks.

Michael


ps. It is finally warm enough in Montreal to take my Spider out, so I might as well to some work on her.

Just got finished staining all the decks on the house. Thirsty work, so this'll be short.

If you have a 74, it already has a relay on the starter circuit. If you want to relieve the relay of CSS current, wire the CSS to the starter terminal of the starter solenoid. That way the battery powering the CSS directly when the starter solenoid is energized. If you have a "click, no crank" problem, it's probably a starter solenoid going south on you. It is possible to open the solenoid and clean the large copper bar and contacts, but you must be careful, because the shaft into the magnet is not very robust.

BTW, I'm personally do not favor additional switches in the CSS circuit. If you look in your owner's manual you'll see the wiring diagram and if you look behind the washer reservoir, you'll see the relay.

Now . . . . where's that beer. . . . .

John-

From the picture it looks like you added the relay, but I thought you were not in favor of that? Did re-wiring the CSS fix the problem? I am not sure how you re-wire the CSS. If my memory is correct, my starter has only two connections: 1. from battery always hot 2. from ignition switch. Clearly you cannot hook the CSS up to #1, and it is already hooked up to #2.

Thanks,

Clark - The relay is original equipment, peculiar to the 74 models. The relay powers the CSS and the starter solenoid. Look at the wire diagram and you'll see the relay.
