I stumbled upon the Bussmann 15303-5 while searching for a solution. This shows real promise. http://offroadpassport.com/forum/showthread.php?t=1228
Anyone know anything about this product?

That particular relay board is located in a 1972 Lotus Europa engine bay. It gets a lot of road spray -- a lot!

I live in the pacific Northwest where it rains a lot. The relay connectors on my MS relay board rusted before our rainy season was 1/2 over. I know some have suggested putting the board inside the vehicle, but I prefer the easy access of having it in the engine compartment. I see a lot of cars with ...

Wouldn't a railgun need something more like 25MF as opposed to 25mF?

Trakkies, I think you hit the nail on the head. What little I can find on capacitance agrees with your recollection. The points condensers seem to be in the 0.1 to to 0.15 uF range. The ones for RFI suppression are a good deal larger, but hard to find the actual spec. I like your suggestion to get a ...

Thanks for the quick reply, Ken. You are right about condenser vs capacitor. Exactly the same thing. However, condenser seems to be the accepted term if your hand fits a wrench, and capacitor if you say things like E = IR. :) Then there are those who can hold a wrench and an ohm meter at the same ...

I believe I found the answer. The forum's search feature did not give the results I needed, but I probably used faulty search criteria. After posting the question, I did an eyeball search and found the capacitor is for noise suppression. My plan is to use a generic noise suppression condenser ...

In the Megamanual wiring diagram for EDIS Ignition Control with Megasquirt II , there is a 25 Micro-farad capacitor between connector pin 8 (and EDIS 6 coil connector 4) and ground. I can't find any info about what kind of capacitor to use. It looks as if it is for noise suppression or possibly to ...

I have thought about buying something like the image below. I already have loop lenses that clip onto the temple bar of my glasses, but they only work for one eye. That's a little tiresome after a while.

I agree about the need for plenty of light and magnification. I can get by without them on all components except the transistors. For them I put inexpensive reading glasses over my regular ones. I also use an additional light on a flexible goose neck. It allows me to put the light right where I need ...

Bridges happen even using the technique outlined in my previous post. I now fix them by remelting the bridge and brushing the joint (while molten) with a small wire brush that was part of a soldering tool kit I found at Radio Shack. They are available from other sources. I couldn't figure out how to ...

I am assembling an MS2 with a V3 board. I'm confused about the first bullet in step 65: " If you are not using the IGBT... ". How do I know if I am or not? I have searched the manual for "IGBT" and the only references are in the text of this step.

Specifically, I'll be using Ford EDIS. I followed ...

I don't think there is a sure way to avoid transistor bridges, but I think I can minimize them using the following:
1. Use a clip-on heat sink to bridge all three leads right under the transistor body.
2. Once the leads have been inserted, turn the board over and bend the outer leads away from the ...

The straight-line layout of transistors just asks for solder bridges. Other boards I've worked with use a triangle layout, which is much easier/safer to assemble. Anyway, I just completed JimStim, and got a bridge across two of the three leads. I fixed it by re-melting the solder and quickly ...
