Cluster confusion

[Goose57]

Hi all I’m trying to get “Wait to Start” light working. According to my owners manual I shouldn’t even have a WTS light just a GP light. There are a couple of stickers on the cluster not sure what they mean. The WTS light was working before. I pulled the cluster and found a wire ( red line ) on the GP light twist socket going to the upshift light twist socket on the grd. side, because the copper trace was damaged, I did repair it.( see pic ). It was labeled upshift, but on the front side it said WTS, what the hell is going ������on? ( see pic) and there was not even a bulb on the GP socket very confusing. I think they were using the GP socket for the damaged copper trace. I put a bulb in the socket marked GP and lit it and there isn’t even anything lit on the front side just blank. WTF. After repairing the copper traces ( I damaged the one in the middle ). ������ and getting the bulb to light on the WTS light ( marked upshift ) turn the key on to start the GP cycle and it blinked once and went out but still completed the cycle then started it and the now the WTS light stays on all the time. I thought for sure after fixing the damaged copper trace and getting the bulb to light during testing I was home free. I did hook up a test light to the WTS pin on the clusters connector in the truck and the test light stayed on during the cycle and after starting it went out like it should, but not when I plug the cluster in. I think I created a monster. I’m trying to find a used cluster and have it remanded but I’m now not sure which part number to get. GM Parts Giant says GM # 16197145 fits my truck but can’t find it. The one in my truck now is a 16176841, maybe it supersets it? I did find one on e bay for a 95’with no WTS light. Only year of OB1 on interior update what ever that means. Sorry boys for the long post. Thanks.

[More Power]

According to my owners manual I shouldn’t even have a WTS light just a GP light.

The "Wait to Start" lamp is the glow plug light. The glow plugs are powered whenever the WTS lamp is illuminated. The lamp itself is tied to the glow plug circuit that feeds the plugs.

If the WTS lamp stays on, the GPs are being powered as well. Not a good thing... While the WTS lamp is illuminated you could use a multimeter to check for battery voltage on the large terminals on the GP relay (which would indicate a stuck relay or powered relay). Beyond testing, I'd not let the glow system remain powered on for long periods.

Thanks for the help. I believe someone was in there revising the cluster back in 98’ see sticker. My truck should have a “Glow Plug” light and not a WTS light. I may have screwed it up trying to repair it. The GP,s are working just not the light. The WTS light may be staying on because of the repair I did, because of the wiring to the cluster being messed w/ during the revision. I am in the process of getting the right cluster form my truck apparently they are rare. Thanks again for your help.
