Last weekend, I put new Wilwood calipers, pads and stainless brake lines on the rear of my 06 Solstice.
On Tuesday, I started seeing an intermittent ABS warning light. Yesterday (Wednesday), I started seeing an intermittent battery light. Late yesterday, the DIC flickered on and off a few times within about 30 seconds, then went back to normal.
The car no longer has an e-brake (waiting on the small calipers and brackets for that), so occasionally the parking brake warning light also comes on when the handle moves up or down due to a bump or hard acceleration.
The engine runs great. No problems starting. Battery is about 10 months old, spent a few months disconnected (positive and negative) while I was rebuilding the engine.
Normally, I'd think this was a failing alternator or a loose ground, but everything else appears to be working fine.
I've put about 600 miles on the car since I put the rebuilt engine in. Problems started a day or two after the new brakes went on.
Also had a CEL for a day that went away on its own. I have an HP Tuners interface, but haven't yet scanned to see what the cause was.
Suggestions? Brake fluid looks good, clutch works fine (shared reservoir).
I also replaced the Solstice dash with one from a Saturn SKY (much cooler), which involved removing and reinstalling the instrument cluster. In this car, everything - speedo,tach etc.) are electronically connected - no hard cables going anywhere. The speedo and tach work perfectly.
Noticed instrument backlight slightly pulsing intermittently.
I love saying "intermittent." Usually leads to "uhhhhh... Dunno." :)
Also, I was in some pretty heavy rain.
