1998 Suburban 350 2WD Multiple Issues [Electric, Power Steering, Starter]

Issues:



  1. When starting vehicle this morning the voltage was showing 18-19+ and the battery light came on. This is the first time it has happened and attempted a restart to no avail. The gauge is moving up/down as I would normally expect (lights turned on, A/C, etc.) however it is showing 4-5V too high. Seems I just need a new alternator but want to make sure there isn't something else I should check first.
  2. The power steering pump needs to be replaced but it appears that I need to pull the entire A/C bracket to get it out, is this accurate? Also is any special tool required to pull the pulley from the pump?
  3. The starter has been acting up for a few weeks prior to #1 (spins but does not engage) so I'll be replacing it but want to verify there isn't something else to check first.

Are items #1 and #3 usual maintenance items that have just occurred together or is there something else I should be looking for? I've never had to replace any of the items since I've owned the vehicle and am not sure if they were done before (bought at just under 100K about 3 years ago).



Thank you in advance for your time,



Joe

This sounds like a voltage regulator. I'm not sure on that vehicle, but it might be integrated with the alternator. Or it might be seperate. Either way, that much voltage is excessive and it can cause other electrical parts to fail. I would resolve this first.

Probably.

It is possible (but unlikely) that the excess voltage could be pushing too much current through the solenoid, thus overheating it, or its contacts might have been damaged. Once again, solve the regulator problem first.

Probably.

Good luck. Let us know how it works out.

phaeton, thanks for the information. Apparently there are three different amp ratings of alternators and mine has the least, 105. The VR is built in so I just picked up a whole new alternator at AutoZone and had it in w/in 20 minutes (unfortunately the power steering won't be as easy). Everything appears to be back to normal and I'll wait to see what happens with the starter.

Enjoy your weekend.

Actually it didn't need to be completely pulled, just pulled off a few bolts (more like 5-8 and a couple of nuts) and the pump dropped out from the bottom but having the bolts off gave the pump a little more wiggle room when trying to get it out.

The starter has continued to have problems, picked one up tonight and will be putting it in as time permits in the next couple of days.
