Question about 1986 Oldsmobile Delta 88
Lights were left on and car battery died. Thirty minutes and about 20 miles of highway driving it had an incident where all electrical went out while the car was slowing down onto an onramp. Moving a battery cable restored lights and radio, wouldn't start again until jumped with cables.Six weeks later after a day of driving and making several stops car has trouble starting. At next destination it died. A jump start got it home and a new battery was installed the next day. Problem today was one week after new battery purchase.

ok; first your car probably has a "rollover switch" this is usally located in the trunk on the right side it can cause this problem but, in your case I think the ground cable that grounds your engine is the culprit check on the engine block for a bolt with a large braided cable that fastens to the frame or sheetmetal of your car remove the bolt(s) and scrape away the paint,grease etc. and, rebolt (the radio is grounded seperately) the gages, lights on dash and, the engine ignition MUST be grounded to the frame to work.

Hi. This issue has several causes, but the oil light indicator is a strong sign of low pressure in the engine. This will cause the engine lubrication rate to drop, thus, producing a illuminated oil light, and erratic Oil pressure readings. The necessary actions are to have a manual oil pressure test ran on this engine, asap. When running a manual oil pressure test, you will discover if the true oil pressure is low, or normal. If the test proves that the oil pressure is, indeed, low, this will confirm that the Oil pump is suspect.
Now, if the true readings given during the manual oil pressure test are indicating that the pressure is normal, this will be the result of a failed sending unit(oil pressure switch). Although the oil pressure is suspect, this is not your only issue here. There seems to be a abnormal compression rate, present. This is causing the rough idle, and erratic RPMs. I recommend to administer a engine block compression test, as well. This test will discover if , indeed, there are issues within the cylinder heads, and block structure, such as a worn head gasket, cylinder wall issues, and cracked block. Normally, these issue will send signs, like white, or gray smoke out the tail pipe, or discolored oil. It will, also, promote erratic RPM ratings, and a rough idle. Have the oil pressure test, and engine block compression test ran, asap.
Once the test are administered, you will be able to isolate the actual problem areas, more accurately. Check the spark plug wire sets, and ignition assembly for faults, also.
