Intalled Coastal EV Mod....not working :(

No. Hymotion.

 

Hmmmm....well for the other 2 wires I used the taps the kit came with. For the pin 27 wire, I used a wire tap that I bought at a local automotive store, the smallest gauge I could find being 16-14 gauge wire taps. That could be my problem right there. They "looked" exactly like the ones that came in the kit....I will order the proper taps then go from there. I will let you know how it goes. It will probably take a few to several days for the taps to arrive.

 

OK Blown240, this is what I did today.

The Coastal Kit has 3 wires coming out of it. I have the appropriate 2 wires (purple and white) spliced into the 2 correct wires (purple and white/black) in the grey plug using a splice appropriate for the wire gauge (i.e. the taps and plugs that came with the kit).

I then disconnected the Coastal wire splice that was spliced into the Hymotion wire leading to pin 27. So now I have an exposed wire (wire that was spliced into Hymotion wire leading to pin 27) in my hand from the Coastal Kit and the other 2 wires appropriately spliced. I plugged the grey jack back in, turned on the car, then touched the third wire (the one that was originally spliced into the hymotion wire in pin 27) to bare metal everywhere I could find....the sheet metal of the car, bolts, a large metal structural bar that runs along the dash, and I got nothing. No beeps, nothing. I even tried pulling the cruise control stalk while touching bare metal and still nothing.

Any ideas as to what I should do next?

 

Coastal e-mailed me back today and said they can't provide advice because I am not installing their device as it was intended, which is true. I can't say I fault them for that answer.

I didn't e-mail anyone at Hymotion yet. I think the best advice about technical stuff like this (combining a Coastal EV device with a Hymotion battery pack) would probably be found here, anyway. When this resource dries up, I will probably try them.

 

Update.........Success!!!

OK guys who are still following along.....I was frustrated so I put the tools away for a few days to think about how I could have screwed things up. First of all, I wasn't "grounding" the way that blown240 told me to upon rereading what he said. Second, there was some conjecture that one of the taps I was using was not the proper gauge.

Well, I unplugged the 'ground' tap and went out and tracked down a tap for 18-22 gauge wire. That took a while as no one had anything smaller than the 16-14 gauge taps. I made a new tap into the wire that went into pin 27 with taps for 18-22 gauge wire, crimped a plug onto the appropriate wire of the Coastal unit, put them together and success. So what it likely was that although I used the correct (supplied) taps on the other plug wires, I had used a 16-14 gauge tap on the pin 27 wire and it wasn't cutting the insulation properly.

So for you amateurs out there like me, even if the taps "look" identical, make sure you use a properly sized tap Thanks to all the posters above who helped me. I owe you all a beer or two or three.....

 

those look like a super pain in the nice person
