Default Magnetic and Non-Magnetic Pickup Values

When trouble-shooting your MSD Ignition and you have a no spark situation make sure your distributor or crank trigger pickup is triggering the ignition. This handy chart will tell you if you pickup has gone bad. All you need is a meter to check the resistance between the pickup. If you using one of our own MSD distributors, it will have a magnetic pickup. If your using a crank trigger it will have a non-magnetic pickup. Use the following chart to find the correct resistance for your pickup thereby letting you know that your ignition is okay and the pickup is bad. Click here for the resistance values.

Default Still No Spark

It won't fire unless I use a hand magnet against the sensor. Stumped.....

Hi, I noticed there are no values for an E-Curve? I need to test my E-curve. It has ran for a year okay but one day I had no spark. Coil seems to read okay, 1.3 ohms primary and 5.6k secondary. Don't know which wires to test on the E-curve it'self. Red, Orange and Black with ohm meter or what readings should be or if I need to rotate the distributor to get readings, etc.

Can you provide this information. Thanks.

On the old style 8505 magnetic crank trigger pickup i get 442 ohms, does this mean it's bad? I can get a spark shorting the purple and orange pickup wires but nothing when cranking even closing up the pickup gap.

hi,

in the link provided it says the 84661 pickup should have a resistance range of 500-700 ohms.

In my aftermarket TSP distributor (not MSD, but i have every reason to believe it is exactly the same pickup; it certainly looks 100% identical), my resistance reading is between 0.751 and 0.765 kΩ. My problem is that i have no spark but my 5520 is sparking the coil correctly (when the spark test is performed).

does this mean the pickup needs replacing? would exposed wire (i.e. plastic insulation stripped partially off the wire at some point, but no chance of short circuit) affect/increase the resistance reading?

thanks

The picture of the distributor and multimeter shows a reading of .59 Kohms. Depending on the meter, you will probably have to use the lowest Kohm range for magnetic pickup readings. So, a reading of .751 K is the same as 751 ohms. The sensor is good.

Default Magnetic pickup 1 hour run time then failure - disappointed to say the least!!!

Hi all,

I just drove my newly completed project for the first time, 7 years in the making. Money was tight hence the long time frame, I brought parts as I could afford them.

I choose an MSD Digital 6 plus to complement my Blaster SS coil & MSD Pro billet distributor # 8589.

The ignition works perfectly until the engine reaches operating temperature & this inturn heats the distributor pickup up, causing it to change from 572 Ohm (cold) to 1.7 Kohm then open circuit. Obviously when this happens, my engine dies, after a long period of time & the pickup cools, it will then restart.

Yes, I brought the ignition around 2 years ago, but only installed it in the last week. Friday being its first drive.

I have contacted your warranty department, but have been told that even though it may have only done 1 hours work its out of warranty. Personally I think this is wrong, a little googling will tell you (especially around the time of my purchase) that I'm not on my own.

I have ordered 2 spares (none of my local retailers stock the MSD magnetic pickup 84661) 1 for now to get it going & 1 as a spare. What happens in 12 or 18 months time when I need the spare & it fails???

I thought msd was meant to be a market leader..... I'm impressed with the product & how it proforms, but 1 hour run time?????


Help Please MSD!!
