+1 on alternator/voltage regulator, you say the lights dim and flare relative to throttle or engine speed, and chances are, if it is starting to fail but not way gone, it wouldn't show on a quickie test at the parts store. The cabling to the alternator would be my second look because increased electrical output may overcome an imperfect connection
Current Volvos:
1998 V70 T5, 112k sat 5 years, still in mechanical coma (finally at the top of the pile )
2004 XC90 T6 AWD: 186k, 60 on transaxle ( traded in )
1998 POS70 N/A: DD/training aid, 236k but really about 240k, I think...ABS module( passed on to son who sold it)
