Re: Replacing Webasto controller and ignition coil with Beckett
Reply #6 –
Update time!
All parts received. Seal on the back side of the fuel pump (don't know if I really needed to, but why not?) and bearings replaced (seemed fine until I took them out, were crunchy).
As far as the beckett stuff goes, I chose to just put the new ignition coil in for the day. I removed the old webasto ignition coil, wires, and electrodes. Unscrewed the electrode connectors to save for later and cut the positive and negative going to the controller wiring (brown and yellow wires). For now, I've run the yellow wire (was going through the burner down near the motor) to a terminal block with the positive (blue/white wire) of the Beckett ignition coil. The old brown negative wire did not seem to provide a sufficient ground so I ran a new ground wire to the bolt on the side of the AH near the relays.
The ignition wires are 14 ga 30kv (2 meters) purchased from amazon. I split this wire in half (1 meter each), put ring wire connectors on one end and screwed the electrodes into the new wire. The Beckett ignition coil has two coil springs on each connector that I twisted off, revealing bolts that the ring wire connectors can be placed upon. A couple of lock nuts keep the wires in place. the electrodes were reattached to the burner and gapped appropriately. the new electrode wires are long enough so they no longer have to stay within the AH unit and the ignition coil can be placed onto the wall or wherever.
So, that being said.. this is a viable option to the folks that have a failing ignition coil and don't want to spend AH money. In hindsite, this is likely all that I needed to do. The difference in spark is night and day. Easily 10x the spark of the old igniter. If this is all you feel you have to do, I would use some 16 ga wire for the positive and negative and the 14 ga 30 kv wire and new ignition coil. That would likely run you under $160.
