I finished putting in led lights in my 1956 Nomad. A few issues but finally got them in. However, now I have no turn signals in the dash. Have dash lights the dim, gen light, oil light, bright and dim headlight-light. But now turn signals. Everything on the outside works. Any ideas and where to look first? Ground problem, light switch. They worked before but not sure if I have a broke wire or what. Thanks in advance for your help.
