RTE Voltage Limiter 3 Question.

I bought an RTE IVR 3 for my 69 barracuda. I'm actually working under the dash now. I tried to contact them with an email and phone call.

Here is my question. The red led light keeps flashing... like a heartbeat when the car key is switched on and also when the car is running. ...............I selected not to reinstall the factory condenser, since the RTE Limiter is solid state. . Anyone else seen that with the RTE limiter?? Again. red LED light continues flashing after about 5 minutes when the car is running.
