Stove Burner Electrodes

I'm wondering about the electrodes for my stove, an Atwood RV-2135 BGP. It's a 3 burner stove with a piezo-electric burner ignitor. Specifically I'm wondering about the electrodes: if they wear out, if they can be adjusted, are they replaceable?

From what I have been able to tell they cannot be purchased separately and are only provided as part of the burner assembly. Has anyone else found to the contrary? It also appears there is no end user adjustment mechanism.

In order to replace one of these electrodes, if even possible, it looks like a tiny clip around its base would have to be removed in order to get it out, then replaced on the new electrode. That seems like a difficult and risky proposition to attempt, and then, again, I have not been able to find replacement electrodes for this stove.

Photo attached, BTW.

While I know some of the tricks to make these finicky piezo ignitors work better such as covering the wires with electrical tape to eliminate arcing to the stove chassis, I'm wondering if the electrode tips get shorter with use and therefore create a larger gap the sparks have to traverse. I could see that reducing the effectiveness of the electrodes.

Hoping to reduce resistance and increase conductivity today I cleaned the underside of the burner lid in the area where the spark travels from the electrode. I also cleaned the tips of the electrodes. It's too soon to know for sure how much that's going to help.

Electrodes are not sold separately.....come with the new burner assembly
Not adjustable

Other then over all length of burner tube and mounting bracket all 3 burners heads are the same

Burner control valves have different size orifices
Left & Right are same and are 6500btu rated
Center is 9000btu rated

Backup tip:
Use BBQ Lighter

Thanks much for the info!

I think I'm going to try installing an electric spark generator. I've ordered one for $10 that runs on an AA battery. It uses different connectors on the ignitor side than does the Atwood piezo-electric ignitor (spade vs. round) but I think I can either modify the exisiting connectors on the wires by squishing them with a pliers thereby changing their shape from round to something more rectangular so that they work with the spade connectors of the spark generator. Other options include buying new wires with the appropriate female spade connectors on both ends or possibly making my own.

The electric spark generator will require drilling out the hole in the face plate of the stove to 7/8". Should I decide for some reason to stay with or go back to the OEM piezo-electric I think the enlarged hole will still be hidden by the OEM knob and the original mounting screw holes should function as they do now.

Spark Generator Installed

UPDATE: I bought. 3 terminal OnlyFire spark generator for $10 and put it in my stove in place of the piezoelectric. It took a little bit of doing to make room for it but it's not a difficult mod. I also made some new ignition wires. Works like a charm and much quieter.
