Limp Mode Adapter

Post by gnulpt »

I am using the Megajolt with internal hard rev limiter.

In this installation, the coil power is routed through the hard rev limiter and is connected to pin 16 of the Megajolt connector.

Unfortnately, that means that one can not simply disconnect the Megajolt and run the EDIS in limp mode since disconnecting would cut the power to the coil pack.

So here is a little adapter I made. This will route the +12V from the input pin 1 to the coil output on pin 16.
Simply unplug the Megajolt and plug the adapter into the harness connector.
Especially when installing the system for the first time, it will help to verify that everything is wired up correctly for the EDIS.
This might also come handy if something goes terribly wrong in the Megajolt.

The plug is a Molex 39-30-0160 PCB header.
Cheap to get. I got mine from Digikey

I just trimmed the soldering wires of the connector, welded a AWG 16 wire between pin 1 and 16 and used shrink tubing to isolate the pins.

Here are some pictures:
