Well, been meaning to get this done for a while. Didn't want the hot start kit from Bosche or the Ford relay, so I found one on line that I liked.
Installed the relay on a small bracket on one of the mounting screws for the relay board. Ran a new small yellow wire to pin 6 of the 12 pin connector and a brown ground wire to the bracket . Ran two 12 ga. wires fron the relay to the solenoid with the hot wire having an inline water resistant ATC fuse holder with a 30 amp fuse. Put some heat shrink around the normally used large yellow wire to protect it. On the solenoid side used tape to protect the connector that used to be hooked to the solenoid. This relay uses 140 mili-amp so not a very large inductive spike to worry about, but I installed a supression diode across the relay coil anyway. Also put a larger one across the solenoid coil at the relay ( 87 to ground). This supresses the solenoid coil inductive spike to protect the relay contacts. here are a few pics, and a link to more info: http://www.google.com/url?sa=t&rct=j&a...eg_6KDxZdKYQYGw This is the aeroelectric link Oh, I tested it several times and it works just fine. Tom Edit: changed back EMF to inductive spike, sorry if this confused anyone. Inductive or transient spike is the correct term for what is happening here Attached thumbnail(s)

Drums,
Thanks for the compliment. (IMG:style_emoticons/default/smile.gif) Yea, by now they are all copies. (IMG:style_emoticons/default/smile.gif) I expect it will last OK, but the next time I order any parts, I will order myself a spare relay just in case. Diodes are cheap at Radio shack, about a buck and the relay was $3.08, already had the wire from the kits for the fuses left over, the inline fuse was $3.29. So all together I have about $10.00 in this mod. I never had the "hot start" problem with this car, just wanted to nip it in the bud so to speak. I can't get the link to transfer but here is the info that really got me interested in doing this modification. aeroelectric.com. Very informative write up. Even mentions that lots of small foreign cars come with no starter relay and end up having key switch problems. Tom |
