I have a Rostra cruise control on my eagle. I lost the magnet strapped to the drive shaft. Can I put any old magnet on it, or do I have to order one from Rostra? It is smaller than the size of a dime. I was hoping Pete could jump in and give me an answer.
Thanks, David
I have several of those magnets from past installations. I could send you one if you'd like.
Darell,
When I saw your post I wondered why you would have those left from past installations, so I checked my bag of left over hardware from my installation 5 years ago, and guess what?, I found 3 magnets left in the bag. Oh lucky day. Thanks for jogging my memory, and I now remember why I never throw anything away.
Thanks,
David
gee - If I wait long enough the problems solve themselves - that's great
actually I don't think it matter very much - almost any small magnet will do

Pete, on a side issue with the Rostra, we had problems with the turn signal switch cancelling the cruise when it was on. Usually, with every lane change.
I studied the diagram and decided that the turn signal switch was doing a break before make when it switched. On thinking about it, I decided to install a single lamp on the brake light circuit to present a path to ground through the bulb for the cruise.
This prevents the cruise from behaving as though a wire to the brake light circuit has broken, and the cruise control works all the time, now.
I did notice that the unit is designed to work with either a grounding brake switch or one that connects to the hot wire.
For what it's worth.

Yes - the Rostra will absolutely disengage if it loses ground from it's BRAKE SENSE WIRE. The Rostra expects a VERY low resistance (like standard brakelights) to ground -
Most After Market cruise controls WILL NOT ENGAGE if you've switched to LED brake lights or tie the Cruise Controls Brake Sense Wire to a small higher resistance panel brake light bulb - You need to add a simple cube relay that will break the cruise control brake sense wire connections to ground.
I've modified my special "ROSTRA HINTS AND TIPS and INSTALLATION for BUS CONVERSIONS " data sheet to reflect this concern.
If anyone wants a copy of my new Rostra data sheet (I'm a Rostra Dealer) - Just give me an email (hawk_ii_mail at Yahoo.com)
I lost the one on my eagle too and I replaced it with a strong magnet that I found at a craft store and it worked like a charm. The Rostra is a good unit if installed correctly.
