Fuse Blowing on Ignitor

Make sure you have good voltage to the burner.

Will check. The power wires to the burner off of the relay have looked a little darkened and crusty for a long time. I'm going to swap everything with 12 gauge. The fuse is past the motor on the ignitor only but the brushes are old. I wonder if I would be able to get brushes that would fit or could be made to fit the motor here in town? The motor looks like it not designed for you to change the brushes - it doesn't have access through the shell like some I have seen - I want to check them but it looks like a royal pain in the azz to stuff the thing back together.

The older motors had access plugs to change brushes, but I guess they weren't selling enough motors.

good idea to upgrade as you go !
Remember..
The true path to strengh, is the elimination of weakness..
Don't just fix it..
Make it better than it was before.. ESPECIALLY heater wiring..
Almost every mfr has had "issues" with reliability.
Let me send you our recommended circuit diagram FREE,
and call me for what's different..
you'll better undrestand why your system failed,
and what to do about it, for "long-term low-cost." Eh?

12volt Burner electrical ..improvements
one more thing...
If you call me from the field,
I’d ask what’s the running voltage of the system.. Check it with a voltmeter.
Whenever it’s a 12 volt burner.. check battery voltage with AND without engine running.
..That proves the charging system..
If you have low voltage for any reason, the system draws extra current (amperage) to have enough “power”..
That blows the fuse. If you use a bigger fuse, you allow more amperage to the devices, which can EASILY burn them up, or at least stress them enough to fail early.. you don’t want that. ..and those overheated wires are proof. Eh?
Those overheated wires are NOT as good a conductor as they were before !
.. Replace EVERY "overheated" wire.
I also have to add.. we use more fuses on our systems than other mfr’s, which makes troubleshooting go much faster, and less expensive.
..and there's NEVER an overheated wire.
You need to know the condition of every terminal and connection.
You can't bank on luck... always do a practical common sense analysis.
..Think about HOW these things work, then communicate with your pit-crew..
Call us anytime… we like to help !

The ignitor is the "weakest link" in the system,
but only because it is sensitive to running on low voltage..
a wimpy switch, a corroded connection, a low battery, a failing charging system.
respect the tech.
