I installed an ignition relay last week. Its pretty easy really, basically you are using the power from the ignition switch (white wire) to turn on the relay and let power from the battery flow to the fuse box and the starter and coil. The advantage of this is that all that power no longer flows through the ignition switch.
The process is pretty straightforward. Incidentally, later model cars came with an ignition relay. My car had had it removed at some point! But adding a relay to an older car makes sense to.

New starter relay
I got a new starter relay today. The old one is on the right, the new one on the left. It cost $3.97 from Advance.
When I went to Advance, they wanted to sell me a $30+ model for the B, and if you look in the Moss or VB catalogs - they also have pretty high priced ones. But it turns out that a relay is a relay and a generic "Bosch" type will do.
It's installed and the engine fires up every time! (well so far).

Ignition problems
Sometimes when I turn the key the starter doesn't turn. But I get a click from the solenoid. I did a bunch of diagnostics and checks.
1. Check all the battery cables and ground strips.
2. Check the connection to the solenoid.
3. Take the brown and white wire on the alternator and ground it then see if the ignition light comes on (this makes sure the ignition light works).
- The light is good but I think I could work on the alternator connections a little - I didn't really clean them that well and I should go back and do it properly.
4. Took it to advance auto parts and had them run a check on the system. Here is the result.
Fascinating stuff. Well it turns out that the starter isn't looking too good. So I took it off and had a look. This is what I found.
So I think I will replace the starter and solenoid. I should be able to get the pair for under $150. The rubber seal is really messed up and the starter is the original lucas one, so it has seen some good service. I'll run by the auto part store and order one this week.
