1: "need to find a mechanic that is skilled in the Base Insight"
-- There is only one guy in the USA, Scott Kulbeck in Covina, California who meets these criteria. The car was low volume, most mechanics have never worked on one before, only about 14000 were sold in the USA. Scott's the only American expert on these cars who is also a mechanic.

2: Your 2001 Insight doesn't have an alternator.
-- All electrical power is generated by the IMA motor which is bolted to the crankshaft between the engine and the transmission. This is routed to the DC/DC inverter in the back of the car and used to charge either the IMA battery or routed back up front to charge the 12v battery.

3: When you start the car is the check engine light and the IMA light on?

Are the red brake and red battery lights coming on at the same time? This would be related to P1449 + low IMA battery voltage causing DC/DC inverter to deactivate. Or you could have bad ground straps which would produce a similar scenario.

I'm guessing you've got check engine light for P1449, unless it's early stage decay which could just have brake//batt lights on + no 12v charging as only symptoms.

I have a couple potential simple fixes for you but I need more diagnosis information -- are the ground straps OK (just open the hood and look at them as described in my first post), what lights remain on after you start the car, and any knowledge you might have about the age of both the hybrid battery and the 12v battery.

I've personally owned 3 of these old Insights, a 2000 and two 2001s, at this age all of these cars have electrical problems, but there's some recommendations I can make (that you can do with no special tools) if you give me a little bit more info.
