1991 xj6 soverign. All gauges, oil speedo, amp, tach, warning lights etc. Were working 2 days ago. Now after having fuel pressure regulator, drivebelts and spark plugs changed, when vehicle is started, NONE of these gauges & lights comes on or works at all, & odometer shows readout that looks like a broken calculator. Access to VCM & reset switch do not work as well. Checked fuses on drivers side & in center console. All have power to them & fuses appear to be good. Whats causing all this?

Figured it out. Bad battery ground. Tightened connections & all gauges, lights worked again. I have 1 other problem. Now all Dash cluster lights stay on when key is removed. What would cuse this? How to fix this.
